Atlanta selected Leon's contract from Triple-A Gwinnett on Monday.

With Sean Murphy (hip) done for the season, Leon will serve as the backup catcher behind Drake Baldwin. Leon went hitless in two plate appearances during a brief stint with Atlanta earlier this season.

Atlanta placed Murphy on the 10-day injured list Monday with a right hip labral tear.

Murphy will undergo surgery Thursday and will need about four months of rehab, which puts him on track to be back to full health for spring training, according to David O'Brien of The Athletic. Per Mark Bowman of MLB.com, Murphy said Monday that the hip injury is something that he's dealt with off and on for the last three years, but it had gotten worse lately to the point that an operation became the recommended course of action. With Murphy out for the season, Drake Baldwin and Marcell Ozuna could see even more playing time for Atlanta down the stretch, and Sandy Leon has been called up from Triple-A Gwinnett to serve as Baldwin's top backup behind the plate.

Vazquez (shoulder) resumed taking part in baseball activities over the weekend and hopes to return from the 10-day injured list by the end of the season, the Phil Miller of The Minnesota Star Tribune reports.

Vazquez has been on the shelf since Aug. 8 due to a left shoulder infection, which he had surgically removed a couple weeks later. He hopes to return for a final few games of the season so that he can show he's healthy as he heads into free agency this winter.

MacIver went 1-for-3 with a solo home run in Sunday's 4-3 loss to the Angels.

MacIver entered Sunday in an 0-for-10 skid. The homer was his third of the year and his first during his current stint on the big-league roster, which has featured sporadic playing time as backup to Shea Langeliers. MacIver is batting .200 with a .639 OPS, nine RBI, seven runs scored, three stolen bases and five doubles across 87 plate appearances in the majors this season.

O'Hoppe (head) is being evaluated for a concussion following Sunday's 4-3 win over the Athletics, Jeff Fletcher of The Orange County Register reports.

O'Hoppe exited the game in the top of the seventh inning after being hit in the head by the backswing of Jacob Wilson. He went 0-for-2 with a walk prior to his departure. Angels interim manager Ray Montgomery said that the catcher is "OK," but the team is likely covering all the bases by having him undergo additional evaluation. O'Hoppe can be considered day-to-day for the time being.

O'Hoppe (head) exited Sunday's contest against the Athletics in the seventh inning, Jeff Fletcher of The Orange County Register reports.

O'Hoppe was struck in the head/neck area by the backswing of Jacob Wilson in the top of the seventh inning, and he ultimately left the contest as a result. The catcher was replaced behind the plate by Travis d'Arnaud, and O'Hoppe's status will likely be updated in the near future.

Kelly went 2-for-4 with two solo home runs in Sunday's 6-3 loss to the Nationals.

Kelly went deep for the second time in his last four games as he registered his third multi-homer performance of the season. The Chicago catcher is up to 16 long balls this year, which is two away from his career high of 18 home runs that he set back in 2019 while playing for the Diamondbacks. Kelly has been a pleasant surprise all season for the Cubs with his .800 OPS, and he should continue to start most days behind the plate moving forward.

Narvaez is out of the lineup for Sunday's game against the Diamondbacks.

Narvaez will get a chance to rest after he caught the first two games of the series and went 1-for-7 with a double, walk and a run scored. Connor Wong will step in behind the plate Sunday and will form a battery with starting pitcher Brayan Bello.

MacIver will start at catcher and bat ninth in Sunday's game against the Angels.

With top backstop Shea Langeliers resting for the day game, MacIver will receive a turn behind the plate. Since being recalled from Triple-A Las Vegas on Aug. 5, MacIver has gone just 3-for-28 (.107 average) with four RBI, two runs and a stolen base in eight games.

Langeliers is out of the lineup for Sunday's game against the Angels.

The Athletics will give Langeliers a breather for the day game after he started at catcher or designated hitter in each of the previous four contests. Willie MacIver will step in behind the dish for Langeliers in the series finale.
