Winston (shoulder) is listed as questionable for Saturday's game at Baltimore, Mary Kay Cabot of The Cleveland Plain Dealer reports.

Winston doesn't appear to be in consideration for the Week 18 start, as coach Kevin Stefanski told Daniel Oyefusi of ESPN.com on Thursday that he intends to play Dorian Thompson-Robinson (calf) and Bailey Zappe under center. As a result, even if Winston is available Saturday, he likely will be the emergency third quarterback, at best.

Richardson (back) remained sidelined at practice Thursday, James Boyd of The Athletic reports.

Richardson was listed as a non-participant in Wednesday's walkthrough, so the QB's absence from Thursday's session puts the focus on what he's able to do Friday in terms of his availability for Sunday's season finale against the Jaguars. If Richardson is unavailable versus Jacksonville, Joe Flacco presumably would draw the Week 18 start for the 7-9 Colts.

Pickett (ribs) didn't participate in Wednesday's walk-through practice.

Head coach Nick Sirianni said earlier Wednesday that many starters won't be available for Sunday's regular-season finale versus the Giants, including starting quarterback Jalen Hurts (concussion/finger) and No. 1 running back Saquon Barkley. Sirianni was also non-committal regarding Pickett's availability for the Week 18 contest, per Martin Frank of The Delaware News Journal. Consequently, the Eagles' practices Thursday and Friday will be key to determining who among Pickett and fellow quarterback Tanner McKee will draw the start under center in Week 18.

Hurts (concussion/left finger) was a non-participant in Wednesday's walk-through practice.

Both Hurts and his primary backup, Kenny Pickett (ribs), didn't take reps to begin Week 18 prep, leaving Tanner McKee as the next man up at quarterback for the Eagles. Head coach Nick Sirianni told Jeff McLane of The Philadelphia Inquirer on Wednesday that Hurts and multiple other starters won't play Sunday against the Giants, but Sirianni didn't rule Pickett out from playing, per Martin Frank of The Delaware News Journal. As a result, Pickett and McKee both look to be possibilities to start under center Sunday at this stage of the week.

Burrow (wrist/knee) was a limited participant at practice Wednesday.

The quarterback will have one more opportunity Thursday to put in a full practice before Saturday's game against the Steelers, but even if he remains limited, his availability for the regular-season finale won't be in much question. The 8-8 Bengals can keep their faint playoff hopes alive with a win, so expect Burrow to play through the pair of injuries, even if he's less than 100 percent healthy.

Winston (shoulder) was a limited practice participant Wednesday, Scott Petrak of the Elyria Chronicle-Telegram reports.

Winston has been listed as a limited participant on both of the Browns' first two Week 18 practice reports, and even if the quarterback is a full participant Thursday, head coach Kevin Stefanski has already said that Winston will likely be inactive for Saturday's season finale versus the Ravens, per Petrak. Dorian Thompson-Robinson (calf) and Bailey Zappe will serve as the Browns' top two quarterbacks this weekend, though Stefanski has yet to name a starter.

Thompson-Robinson (calf) was a limited practice participant Wednesday, Scott Petrak of the Elyria Chronicle-Telegram reports.

Thompson-Robinson played through the same calf injury during Sunday's 20-3 loss to Miami, completing 24 of 47 passes for 170 yards and an interception while running four times for 10 yards and losing a fumble. Browns head coach Kevin Stefanski said he's unsure about who will start at quarterback in Week 18 against the Ravens, and he floated the possibility of both Thompson-Robinson and Bailey Zappe seeing reps in Saturday's season finale.

Mahomes (ankle) was a limited participant at practice Wednesday.

Mahomes has been managing a mild high-ankle sprain since suffering the injury in a Week 15 win over the Browns, but he's proceeded to play in both of the Chiefs' last two contests while turning in two of his best performances of the season. His listed limitations for Wednesday are likely maintenance-related more than anything and won't have any bearing on his status for Sunday's regular-season finale versus the Broncos, with head coach Andy Reid having indicated that Mahomes will be rested for the contest. With the Chiefs having clinched the No. 1 seed in the AFC playoffs, Mahomes will get some extra time to heal in Week 18 before returning to action in the divisional round of the postseason. Carson Wentz is slated to draw the start at quarterback Sunday in Denver.

Maye was a limited participant at practice Wednesday due to a right hand injury.

Maye left this past Saturday's 40-7 loss to the Chargers at one point to undergo a concussion evaluation, but he was cleared to re-enter the game. He's apparently emerged from the Week 17 contest with a hand injury, but the expectation is that Maye will start Sunday's season finale against the Bills, after head coach Jerod Mayo said earlier Wednesday that he's planning on having all of the Patriots' healthy starters take the field in Week 18, per Mike Reiss of ESPN.com. Assuming Maye is able to advance to full practice participation by Friday and avoids an injury designation, he should direct the offense Sunday, though it's possible that rookie sixth-round pick Joe Milton seems some snaps under center at some point during the contest.

Richardson (back) was listed as a non-participant after Wednesday's walk-through practice, but Colts head coach Shane Steichen hopes the quarterback can play Sunday against Jacksonville, Amanda Foster of the team's official site reports.

Richardson revealed Wednesday that he was barely able to walk last Tuesday because the pain from a disc issue in his back was so bad. He said he's feeling "way better" this week and will try to play in the season finale, hoping to finish out a disappointing campaign with a strong individual performance and a Colts win. Richardson also revealed that he's dealt with back spasms since eighth grade and has issues that "might be chronic," but won't necessarily require surgery, per James Boyd of The Athletic. None of this is good news for his long-term outlook, nor for his Week 18 rushing projection if he plays.
