Olson has been given a platelet-rich plasma injection in his injured right shoulder, Chris McCosky of The Detroit News reports.
Olson will not require surgery for his right shoulder strain, but he has already been ruled out for the remainder of the regular season. The hope is that the PRP injection will help speed along the healing process and give Olson a chance to return at some point during the postseason, should the Tigers make a playoff run.

Tigers' Reese Olson: Will not require shoulder surgery
Rotowire
Olson will not require surgery to repair his injured right shoulder, Cody Stavenhagen of The Athletic reports.
The hurler is still awaiting final word on his latest medical evaluation before a path for his rehab is determined, but the good news is that surgery will not be necessary. Olson has already been ruled out for the remainder of the regular season, but he hopes to be available at some point in October if the Tigers make a postseason run.

Tigers' Reese Olson: Out for rest of regular season
Rotowire
Tigers president of baseball operations Scott Harris said Monday that Olson has been placed on the 60-day injured list and will miss the rest of the regular season due to a right shoulder strain, Cody Stavenhagen of The Athletic reports.
According to Evan Petzold of the Detroit Free Press, the Tigers are still leaving the door open for Olson to return for the postseason, though even if he's back in action by October, the right-hander could be limited to a relief role. Olson wasn't known to be dealing with an injury, but the shoulder strain helps explain why he was uncharacteristically lacking in command during his most recent start Thursday, when he was handed a loss against the Blue Jays after allowing five earned runs on six hits -- including two home runs -- and two walks in 5.2 innings. The Tigers acquired right-hander Chris Paddack from the Twins on Monday, and he'll end up taking over Olson's spot in the rotation.

Tigers' Reese Olson: Falters in defeat
Rotowire
Olson (4-4) took the loss after throwing 5.2 innings, allowing five runs on six hits and two walks while striking out four, during Thursday's 11-4 loss to the Blue Jays.
The normally reliable Olson faltered Thursday against the surging Blue Jays, allowing a season-high five runs in 5.2 innings of work. In particular, the home runs are what hurt the 25-year-old, as he surrendered two long balls this start after giving up only three entering the game all season. The right-hander's streak of nine straight starts allowing three runs or fewer is over, and he's scheduled to have a chance to restart that streak at home against the Diamondbacks on Tuesday.

Tigers' Reese Olson: Six Ks in five scoreless innings
Rotowire
Olson took a no-decision Friday against the Rangers, giving up two hits and one walk in five scoreless innings. He struck out six.
Friday represented the fifth scoreless start of the season for Olson, who also recorded at least six punchouts for the fifth time this year. The right-hander produced 13 whiffs as well, and he's now been able to work at least five frames in eight of his 12 outings this season. Olson will carry a strong 2.71 ERA, 1.19 WHIP and 61:23 K:BB over 63 innings into his next scheduled start, which projects for a soft matchup against the Pirates in Pittsburgh.

Tigers' Reese Olson: Needs one more rehab start
Rotowire
Tigers manager A.J. Hinch said Friday that Olson (finger) is expected to require one more rehab start before being activated from the 15-day injured list, Evan Petzold of the Detroit Free Press reports.
Detroit optioned No. 5 starter Keider Montero to Triple-A Toledo on Friday, but that apparently won't be a precursor to Olson being activated during the upcoming week. Instead, Olson will most likely make his third rehab start for Toledo this Tuesday or Wednesday, and if he checks out fine, he'll presumably be activated from the IL during the first week of July. Olson, who has been on the shelf since May 19 due to right ring finger inflammation, most recently tossed 3.2 scoreless innings and 58 pitches for Toledo on Thursday, allowing three hits and no walks while striking out five.

Tigers' Reese Olson: Starting rehab assignment
Rotowire
Olson (finger) will begin a rehab assignment with Triple-A Toledo on Saturday, Evan Woodbery of MLive.com reports.
Olson has been sidelined since May 19 due to right ring finger inflammation, but he's made enough progress with his throwing program to test himself in a game setting. General manager Jeff Greenberg said Sunday that he's "cautiously optimistic" that Olson will return from the injured list "sooner rather than later," though he may require multiple appearances at Triple-A before being cleared to join the big-league rotation.

Tigers' Reese Olson: Completes side session
Rotowire
Olson (finger) threw a bullpen session Saturday without issue, MLB.com reports.
Olson didn't throw his changeup during the session, as his inflamed right ring finger is still preventing him from using his full arsenal in workouts. That said, general manager Jeff Greenberg noted Sunday that he's "cautiously optimistic" that Olson will return from the injured list "sooner rather than later." Olson could be ready to mix in his changeup during his next throwing session, and if that goes well, he could advance to facing hitters in live batting practice.

Tigers' Reese Olson: Receives injection for finger
Rotowire
Olson received an injection to address the inflammation in his right ring finger Monday and is expected to resume playing catch Thursday, Chris McCosky of The Detroit News reports.
The right-hander landed on the shelf with the injury May 19, and the inflammation apparently returned after he was briefly shut down from throwing. Olson is without an official timeline for his return but will likely be out for at least a couple more weeks as he ramps his throwing program back up.

Tigers' Reese Olson: Resumes throwing
Rotowire
Olson (finger) threw on flat ground Thursday, Chris McCosky of The Detroit News reports.
Thursday marks the first time Olson has done any sort of throwing since he landed on the injured list Monday due to inflammation in his right ring finger. The right-hander is confident he won't need to spend much more than the 15-day minimum on the IL, though he'll need to start throwing off a mound soon for that to be a realistic possibility.

Tigers' Reese Olson: Strong start wasted Saturday
Rotowire
Olson came away with a no-decision in Saturday's 2-1 loss to the Blue Jays, scattering one hit and one walk over six scoreless innings. He struck out six.
The right-hander faced only one batter above the minimum and didn't let a Toronto runner get past first base in his third quality start of the season, but Olson saw his fifth win of the year slip away when the Detroit bullpen fell apart late. He's blanked the opposition in four of his last six trips to the mound, posting a 1.60 ERA, 0.95 WHIP and 38:11 K:BB through 33.2 innings over that stretch. Olson will look to keep rolling in his next start, which lines up to come at home next week against the Guardians.

Tigers' Reese Olson: Struggles early in loss
Rotowire
Olson (4-3) took the loss against the Rangers on Sunday, allowing three runs on seven hits and one walk with five strikeouts over four innings.
Olson surrendered a two-run homer in the second inning, and then yielded another run in the third. It was the 25-year-old's shortest outing of the season, as he generated only eight whiffs on 83 pitches and dealt with frequent traffic on the basepaths. He'll carry a 3.38 ERA, 1.29 WHIP and 45:18 K:BB across 42.2 innings into a road matchup with the Blue Jays next weekend.

Tigers' Reese Olson: Cruises to fourth win
Rotowire
Olson (4-2) got the win over the Angels on Sunday, tossing 5.2 scoreless innings while allowing three hits and three walks. He struck out eight.
Olson posted his third scoreless start this season of at least five innings. Sunday was also his third straight start with at least seven strikeouts, as his swing-and-miss stuff has taken a noticeable jump from last season. Over his last four outings, Olson has a 1.14 ERA, 0.93 WHIP and 27:9 K:BB in 23.2 innings. He lines up for a home matchup against the Rangers in his next start.

Tigers' Reese Olson: Collects win in quality start
Rotowire
Olson (1-1) picked up the win Saturday, allowing two runs on seven hits and three walks over six innings in a 7-2 victory over the White Sox. He struck out five.
The right-hander had trouble harnessing his control, tossing only 52 of 94 pitches for strikes, but he got plenty of run support and held on long enough to record his first quality start and victory of 2025. Olson has had a bumpy start to his season, posting a 5.06 ERA and 10:5 K:BB through his first 10.2 innings. He's scheduled to make his next outing on the road next weekend in Minnesota.

Tigers' Reese Olson: Concludes spring schedule
Rotowire
Olson allowed two runs on four hits across 5.1 innings in Sunday's Grapefruit League game against the Phillies. He walked two and struck out three.
Olson wrapped up a solid spring slate in which he recorded a 4.30 ERA and 13 strikeouts across 14.2 innings. The righty is in line to serve as Detroit's No. 3 starter this season behind Tarik Skubal and Jack Flaherty, with his debut likely coming on Saturday against the Dodgers on the road. Olson has posted sub-4.00 ERAs in each of his first two MLB campaigns, though he's a risky play against the loaded Los Angeles lineup.

Tigers' Reese Olson: Looks sharp in spring start
Rotowire
Olson tossed three scoreless innings in Wednesday's Grapefruit League game against the Phillies. He allowed one hit and struck out four.
Olson's second spring start was better than his first, when he allowed two solo home runs across two innings of work. The righty has been a nice find for the Tigers, as he posted sub-4.00 ERAs in each of his first two seasons with the team, including a 3.53 ERA in 2024 across a career-high 112.1 innings. Olson isn't flashy, but he should be a steady option as Detroit's No. 3 starter this year behind Tarik Skubal and Jack Flaherty.

Tigers' Reese Olson: Activated ahead of Monday's start
Rotowire
The Tigers activated Olson (shoulder) from the 15-day injured list Monday, Chris McCosky of The Detroit News reports.
Olson is set to rejoin the rotation Monday versus the Royals after missing nearly two months with a right shoulder strain. The right-hander went just three innings and threw 45 pitches in his last rehab start, so he will be pretty limited Monday from a workload perspective.

Tigers' Reese Olson: Likely returning next week
Rotowire
Olson (shoulder) is trending towards a return early next week in Kansas City, Chris McCosky of The Detroit News reports.
McCosky hints than an announcement will come Saturday, and given that Tarik Skubal has been confirmed to start Wednesday, that leaves Monday or Tuesday as potential dates for Olson to make his return to the rotation. He struck out five across three scoreless frames in his rehab start Tuesday for Triple-A Toledo.

Tigers' Reese Olson: Throws 39 pitches in rehab start
Rotowire
Olson (shoulder) allowed one hit and one walk while striking out one across two scoreless innings in a rehab outing with Triple-A Toledo on Thursday.
Olson pitched in his first game since landing on the injured list July 21 and tossed 39 pitches, 24 of which went for strikes. He averaged 94 miles per hour on his fastball -- in line with his norms for the season -- and threw all of his pitches. Olson will still require a couple more rehab outings, but a return from the IL in late September appears realistic.
