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.

The Dolphins cut Conner from the practice squad Wednesday.

Conner was brought back by Miami on the practice squad in early November after being waived from the team's active roster, but he'll now be on the lookout for a team in need of depth at tight end. He appeared in each of the Dolphins' first nine games of the regular season, splitting his time between special teams and offense and accumulating nine catches (on 15 targets) for 91 yards.

Gordon (ankle) was a full participant in Wednesday's practice, David Furones of the South Florida Sun Sentinel reports.

Gordon sustained an ankle injury midway through the second quarter of Monday's loss to the Steelers. His full practice Wednesday indicates that the injury isn't a concern for the rookie sixth-rounder, which puts him on track to play Sunday against the Bengals. Gordon has turned 60 carries into 191 yards and three touchdowns and six catches (one eight targets) for 30 yards and one score through 14 regular-season games.

Moore (elbow) logged a full practice Wednesday.

Moore has been sidelined since Week 5 with an elbow injury and was designated to return from injured reserve Wednesday. The fact that he logged a full session suggests he has a chance to return in Week 16 against Tampa Bay, though he'll need to be activated from IR by Saturday evening.

The Saints are expected to sign Hines to the practice squad, Adam Schefter of ESPN reports Wednesday.

Devin Neal (hamstring) has already been ruled out for Sunday's game against the Jets and Alvin Kamara (knee/ankle) has been sidelined for the Saints' last three games, leaving Evan Hull and Audric Estime as the only healthy running backs on New Orleans' active roster. Hines appeared in three regular-season games for the Chargers earlier in the season before being cut from the practice squad in late October, but the veteran running back is poised to get another chance with the Saints. Assuming he's signed to the Saints' practice squad, he could be elevated for Week 16 to provide New Orleans another option out of the backfield and a returner on special teams.

Smyth is expected to be signed to the Saints' active roster this week, Katherine Terrell of ESPN.com reports.

Smyth has been elevated from the practice squad to serve as the team's starting kicker each of the last three weeks, going 4-for-5 on field-goal attempts, including a 56-yard make. The 24-year-old has now exhausted all three of his elevations and in order to appear in another contest, the team will have to officially sign him to the active roster, which head coach Kellen Moore stated is coming in the near future.

Chandler (knee) logged a full practice Wednesday,

Chandler has been practicing for most of December after he was designated to return from injured reserve. It remains unclear if he'll be activated ahead of Minnesota's Week 16 matchup against the Giants, and he'd likely return primarily to special teams duties.

Luepke (concussion) did not practice Wednesday, Clarence Hill Jr. of AllDLLS.com reports.

Luepke entered the league's concussion protocol during the Cowboys' Week 15 loss to the Vikings. Even if he were to return to practice over the next two days, Luepke would have to be cleared from the league's protocol by an independent neurologist in order to play Sunday against the Chargers. The Cowboys don't have another fullback on the active roster or practice squad, so they may deploy a tight end like Luke Schoonmaker or Brevyn Spann-Ford as a backfield blocker if Luepke is not cleared to play.

Harris (hip) was a limited participant at practice Wednesday.

Harris reeled in three of five targets for 49 yards in the team's Week 15 win over the Chiefs, but he may have suffered a hip injury in the process. With Quentin Johnston (groin) and Derius Davis (ankle) still banged up, the Chargers could be thin at wide receiver in Week 16 if Harris is forced to be sidelined. Harris will have two more chances to log a full practice before Sunday's matchup with the Cowboys.

Vannett (oblique) does not carry an injury designation into Thursday's game against the Seahawks, Gregg Bell of The Tacoma News Tribune reports.

An oblique injury limited Vannett's participation in Monday's and Tuesday's walkthrough practices, but the veteran tight end has been cleared to play in Week 16 after logging a full practice Wednesday. He's mostly served on special teams this season and will operate as the Rams' TE4 behind Colby Parkinson, Terrance Ferguson and Davis Allen for Thursday night's game.
