The Dolphins elevated Thompson from their practice squad to their active roster Saturday.

With Tua Tagovailoa (hip) deemed doubtful for Sunday's matchup versus the Jets, Tyler Huntley will likely start at quarterback for Miami. As a result, Thompson is probably going to be needed to serve as the team's backup signal-caller. Thompson made a start in Tagovailoa's stead Week 3 versus Seattle, but he has logged just two offensive snaps without throwing a pass since then while Huntley has emerged as the Dolphins' preferred No. 2 QB.

Rush may start Sunday's game versus the Commanders, but backup QB Trey Lance is expected to earn "significant" snaps as well, Ian Rapoport of NFL Network reports.

Rush has taken on the vast majority of QB reps since Dak Prescott (hamstring) was lost for the season in the second half of a Week 9 loss in Atlanta. In parts of nine games in the interim, Rush has completed 60.5 percent of his passes, averaged 199.1 yards per game and put together a 12:4 TD:INT. He's also notched 17 yards on 24 carries and fumbled nine times (three lost). With the Cowboys out of the playoff picture, it appears the team wants to see what Lance can do with more than the three brief appearances he's made so far this season, but it's also unclear how much he'll eat into Rush's typical workload.

Lance is expected to see "significant" snaps during Sunday's season finale against the Commanders, Ian Rapoport of NFL Network reports.

Even with No. 1 QB Dak Prescott sidelined since he suffered a season-ending hamstring injury Week 9, Cooper Rush has handled just about all the reps under center in the meantime, while Lance has completed five of seven passes for 22 yards, no touchdowns and an interception and recorded five carries for 15 yards in three mostly brief appearances. Rapoport also noted that Rush still may start Week 18, but Lance should receive plenty of run to see how he handles extended game action. The breakdown of reps between Rush and Lance hasn't been made clear, though, so it remains to be seen what kind of workload either player will have Sunday.

Purdy (elbow) has been ruled out for Sunday's game against the Cardinals, Nick Wagoner of ESPN.com reports.

Head coach Kyle Shanahan made it clear earlier in the week that Joshua Dobbs would start the final regular-season game. Purdy banged his right throwing elbow toward the end of a Week 17 loss to the Lions, missing the final few minutes after playing well for most of the night. San Francisco general manager John Lynch said Friday that Purdy's injury isn't anything serious and isn't related to his 2023 elbow surgery, per Cam Inman of The San Jose Mercury News. Purdy should be fine for the start of the offseason program.

Tagovailoa (hip) is listed as doubtful for Sunday's game at the Jets, David Furones of the South Florida Sun Sentinel reports.

Tagovailoa's listing on the Dolphins' final Week 18 practice report isn't a surprise after coach Mike McDaniel told Travis Wingfield of the team's official site on Friday that it's "unlikely that Tua will see any action" Sunday. McDaniel also spoke of Tagovailoa's particular injury. "I wouldn't say it's a bruise, but it's kind of a unique muscle issue as a result of the hip," McDaniel relayed to Marcel Louis-Jacques of ESPN.com. Assuming Tagovailoa is among Miami's list of inactives about 90 minutes before Sunday's 4:25 p.m. ET kickoff, as expected, Tyler Huntley will earn a second start in a row.

Mahomes (ankle) is listed as doubtful for Sunday's contest at Denver.

Speaking to the media Friday, coach Andy Reid effectively ruled out Mahomes for Week 18 action, per Charles Goldman of AtoZSports.com. Having said that, the Chiefs may not make it official until about 90 minutes before Sunday's 4:25 p.m. ET kickoff. In any case, Carson Wentz is set to lead Kansas City's offense this weekend, but with RB Isiah Pacheco (ribs) also sidelined and TE Travis Kelce and RB Kareem Hunt listed as doubtful (meaning they'll likely be healthy scratches), Wentz will be working without a few key skill-position players. As for Mahomes, he'll turn his focus to the divisional round on either Jan. 18 or 19.

Trubisky is expected to play in Sunday's game against the Patriots once starter Josh Allen exits the game, but Trubisky may end up also ceding some snaps to Mike White, whom Buffalo signed off its practice squad Friday, Alec White of the Bills' official site reports. "We hope we can get him in the game," head coach Sean McDermott said of White.

Though Allen will open the game under center to extend his streak of regular-season starts to 104, he's likely to play only a possession or two while the Bills are locked in as the No. 2 seed in the AFC playoffs. The Bills are thus expected to essentially treat Week 18 as a preseason game, meaning that Trubisky should get a good look once Allen leaves the game, but Trubisky may also yield snaps to White at some point in the second half. While Trubisky is a capable backup who has displayed some rushing ability during his career, his fantasy appeal in Week 18 will be limited by the fact that he won't start and because he may not be guaranteed to see the overwhelming majority of snaps if the Bills elect to use White.

Pickett (ribs) is listed as questionable for Sunday's contest versus the Giants.

Despite not practicing this week due to a rib injury, Pickett has been given a chance to be available, at the very least, for the Eagles' regular-season finale. With Jalen Hurts (concussion/left finger) out for a second consecutive game, a healthy Pickett likely would be getting the nod under center Week 18, but fellow reserve Tanner McKee relayed to Eliot Shorr-Parks of Sports Radio 94 WIP Philadelphia on Friday that he's preparing for his first NFL start. As a result, Pickett may be McKee's direct backup Sunday or even inactive as the emergency third QB behind McKee and Ian Book, assuming Pickett suits up.

Hurts (concussion/left finger) has been ruled out for Sunday's contest against the Giants.

Hurts hasn't practiced since sustaining a concussion while taking a big hit in the first quarter of a Week 16 loss at Washington. He thus will miss a second game in a row to end the regular season, and his backup Kenny Pickett (ribs), who also didn't practice this week, is listed as questionable for Week 18. Even if Pickett is active for Sunday's 1 p.m. ET matchup, he may be no more than the No. 2 quarterback to Tanner McKee, who told Eliot Shorr-Parks of Sports Radio 94 WIP Philadelphia on Friday that he's preparing for his first NFL start. As for Hurts, he'll turn his focus to getting ready for the wild-card round against the to-be-determined No. 7 seed in the NFC.

Rattler will remain the starting quarterback Sunday against the Buccaneers, as Derek Carr (hand) has been ruled out, Nick Underhill of NewOrleans.Football reports.

Rattler will make his sixth NFL start, having lost the first five. Including one relief appearance, the rookie fifth-round pick has posted a 3:5 TD:INT. The banged-up Saints will face an uphill battle Sunday on the road against a Buccaneers team that would clinch a playoff berth with a win.
