San Francisco signed Martinez to its practice squad Wednesday, Kyle Madison of USA Today reports.

Just a day after being waived from the Jets' practice squad, Martinez is now back with the 49ers, who also cut him from their practice squad less than two weeks ago. With starter Brock Purdy and backup Mac Jones both healthy, Martinez is likely a couple injuries away from seeing any game action for the rest of the season.

Smith (shoulder/back) practiced fully Wednesday.

Adam Schefter of ESPN previously reported that coach Pete Carroll said there was "a good chance" that Smith would rejoin the lineup Sunday against the Texans, and the QB's full practice participation Wednesday sets the stage for that to occur. With Smith inactive in Week 15, Kenny Pickett struggled to get the Raiders offense going in a 31-0 loss to Eagles (the team's eighth straight defeat). In his looming return to action, Smith merits fantasy consideration only in deeper, QB-friendly formats while facing a stout Houston defense.

Taylor (groin) was estimated as a limited participant at Wednesday's walk-through practice, Rich Cimini of ESPN.com reports.

Jets head coach Aaron Glenn has already stated that Brady Cook will start Sunday versus the Saints, but one of Taylor or Justin Fields (knee) will operate as the No. 2 quarterback, health depending. A knee injury suffered Week 14 against the Dolphins prevented Taylor from taking the field during New York's loss to Jacksonville in Week 15.

Fields (knee) is listed as a limited participant on Wednesday's walk-through practice report, Rich Cimini of ESPN.com reports.

Fields and Tyrod Taylor (groin) were both limited in practice Wednesday, though jets head coach Aaron Glenn has already named Brady Cook the starter for Sunday's game against the Saints. Which of Fields or Taylor is named the No. 2 quarterback behind Cook will depend on which signal-caller is deemed healthiest.

Dolphins head coach Mike McDaniel said Wednesday that Tagovailoa will act as the emergency No. 3 quarterback during Sunday's game against the Bengals, Omar Kelly of the Miami Herald reports.

Tagovailoa will not only be benched in favor of rookie seventh-round pick Quinn Ewers versus Cincinnati in Week 16, but he's positioned to be inactive while Zach Wilson remains in the backup role. In that case, Tagovailoa would only be eligible to take the field if both Ewers and Wilson end up forced out of action. Based on the timing of his benching, it won't be surprising if Tagovailoa remains in the No. 3 role for Miami's remaining three regular-season games. Across 14 appearances this year, Tagovailoa has thrown a career-high and league-leading 15 interceptions. If he doesn't take another snap in 2025, Tagovailoa with end the season with a 68 percent completion percentage, 2,660 passing yards and 20 touchdowns, in addition to the aforementioned INTs. He's also rushed 20 times for 43 yards and fumbled eight times, losing one.

Dolphins coach Mike McDaniel said Wednesday that Wilson will remain the No. 2 quarterback behind new starter Quinn Ewers during Sunday's matchup against the Bengals, while Tua Tagovailoa will act as the emergency No. 3 quarterback, Alain Poupart of SI.com reports.

Wilson signed a one-year, $6 million contract with Miami this offseason and has acted as the team's backup quarterback for almost all of the 2025 campaign, but it's Ewers, a rookie seventh-round pick, who has looked more impressive at practice and now gets the starting nod with Tagovailoa benched. That said, Ewers likely won't have much margin for error if he struggles to move the offense early, so it's not inconceivable that Wilson gets a chance to show what he can do under center across the course of the Dolphins' final three regular-season games.

Fields (knee) won't start Sunday's game at New Orleans but could be active as the backup if he's healthy, Al Iannazzone of Newsday reports.

Brady Cook will start, with the backup situation apparently depending on who of Fields or Tyrod Taylor (knee) is healthier.

Jackson missed Wednesday's practice due to flu-like symptoms, Cordell Woodland of 105.7 The Fan Baltimore reports.

Ravens coach John Harbaugh didn't sound too concerned, but it's perhaps worth noting that Jackson has missed an unusual amount of time (mostly practices) due to illnesses throughout his career. The good news for Baltimore is that Jackson got sick early in the week, giving him at least four full days to recover before the Ravens face the Patriots on Sunday night.

Taylor (groin) won't start Sunday's game at New Orleans but could be active as the backup if he's healthy, Al Iannazzone of Newsday reports.

Jets coach Aaron Glenn named Brady Cook as his Week 16 starter, with the backup situation depending on injuries to Taylor and Justin Fields (knee). Either way, Taylor isn't assured of seeing the field again this season.

Smith (shoulder/back) is returning to practice Wednesday, Ryan McFadden of ESPN.com reports.

Smith didn't practice at all last week, yet Raiders coach Pete Carroll said the veteran QB had "a really good chance to be back" for Week 16 against the Texans. It's arguably a matchup between the NFL's best defense and worst offense, but Smith's presence would at least be good news for fantasy managers that are relying on TE Brock Bowers or RB Ashton Jeanty.
