Winston (coach's decision) is inactive but available as New York's emergency third quarterback Thursday night against the Eagles, Dan Salomone of the Giants' official site reports.

Winston will continue to operate as New York's No. 3 option at quarterback in Week 6. The 31-year-old will only be eligible to play if both Jaxson Dart and Russell Wilson are forced to exit early.

Howell (coach's decision) is inactive but available as Philadelphia's emergency third quarterback Thursday night versus New York.

Howell will once again operate as the No. 3 quarterback in Week 6, and he'll only be eligible to enter the game if both Jalen Hurts and Tanner McKee go down with injuries. Howell has yet to appear in a regular-season game since being traded to Philadelphia in August.

Tagovailoa (hip/left thumb) practiced fully Thursday, David Furones of the South Florida Sun Sentinel reports.

After being limited Wednesday, Tagovailoa's full participation a day later paves the way for him to be ready for Sunday's game against the Chargers, who have dropped two straight games. In terms of the issue with the left thumb on Tagovailoa's throwing hand, Furones previously noted that the QB didn't appear to be hindered on short/intermediate throws during Thursday's session. With Tyreek Hill (knee) out for the season, Tagovailoa's top playmakers going forward figure to be WR Jaylen Waddle, RB De'Von Achane and TE Darren Waller.

Jones (knee/oblique) officially was limited at Thursday's practice, Vic Tafur of The Athletic reports.

Jones emerged from his third start of the season in place of QB Brock Purdy (toe) last Thursday at the Rams with an oblique injury in addition to the existing PCL sprain. On Thursday in particular, Jones didn't attempt many throws in the portion of the session open to the media, per David Lombardi of SFStandard.com. While Purdy appears to be trending toward another absence Sunday at Tampa Bay, Jones himself needs to be monitored as the weekend approaches to ensure he's lined up to be under center yet again.

Jones (knee) was in uniform for Thursday's practice but didn't attempt many throws, Nick Wagoner of ESPN.com reports.

The 49ers appear to be taking it easy on Jones in the likely scenario that No. 1 QB Brock Purdy (toe) isn't able to play Sunday at Tampa Bay. Notably, Adrian Martinez was the only quarterback to throw during route-running work Thursday, per David Lombardi of SFStandard.com, so Jones seems destined to log a second consecutive limited session. Friday's practice report will be key to determining who will be under center for San Francisco this weekend.

Purdy (toe) didn't practice Thursday but was seen doing some conditioning work while wearing cleats, Cam Inman of The San Jose Mercury News reports.

Purdy has missed three of the last four contests due to a turf toe injury, and his lack of practice reps so far this week seems to indicate he's trending toward another absence Sunday at Tampa Bay. Coach Kyle Shanahan told David Lombardi of SFStandard.com on Wednesday that Purdy is "progressing," and the 49ers haven't considered placing the quarterback on injured reserve, which would carry with it a minimum four-game absence. As a result, even if Mac Jones ends up getting the Week 6 start under center for the 49ers, Purdy remains a candidate to play until the team officially rules him out for game day.

Jackson (hamstring) remained sidelined at practice Thursday, Jamison Hensley of ESPN.com reports.

With Jackson having yet to practice in any fashion since injuring his hamstring in the Ravens' Week 4 loss to the Chiefs, Jackson appears to be trending toward missing a second straight game Sunday against the Rams. If Jackson ends up being ruled out for the Week 6 contest, Cooper Rush would be on track for another starting turn for the Ravens before the team heads into a Week 7 bye.

Murray (foot) didn't practice Thursday, Darren Urban of the Cardinals' official site reports.

Murray hasn't practiced so far this week due to the foot injury that forced him out for three snaps during this past Sunday's 22-21 loss to the Titans. He thus has one more opportunity to mix into drills Friday before Arizona potentially makes a ruling on his status for Week 6 action. If Murray sits out Sunday's game at Indianapolis, veteran signal-caller Jacoby Brissett is waiting in the wings to lead the Cardinals offense.

Tagovailoa (hip/left thumb) was limited at practice Wednesday, Marcel Louis-Jacques of ESPN.com reports.

Tagovailoa, who is coming off a 256-yard, three-TD effort in the Dolphins' 27-24 loss to the Panthers this past Sunday, is now managing two injury concerns ahead of this Sunday's contest against the Chargers. While so far there's nothing to suggest that the QB's Week 6 status is in any danger, Tagovailoa will likely need to practice fully by Friday in order to avoid carrying an injury designation into the weekend.

Coach Kyle Shanahan said Jones (knee/oblique) will be limited in practice Wednesday, Matt Barrows of The Athletic reports.

Jones endured a number of big hits and also dealt with dehydration during last Thursday's 26-23 overtime road win against the Rams, but he didn't miss any of the 49ers' 86 offensive snaps and completed 33 of 49 passes for 342 yards, two touchdowns and no interceptions. Brock Purdy's lingering turf toe injury has afforded Jones three starts through five games this season, and Purdy remains sidelined at practice as of Wednesday. If Purdy requires more time to recover, Jones appears set to continue leading San Francisco's offense Sunday in Tampa Bay.
