Herbert (ankle/thigh) won't practice Wednesday, Eric Smith of the Chargers' official site reports.

Chargers head coach Jim Harbaugh said earlier Wednesday that Herbert is dealing with a left ankle injury unrelated to the one he dealt with earlier this season, as well as a leg contusion, per Daniel Popper of The Athletic. Herbert left Sunday's loss to the Chiefs in the second quarter, but then returned in short order and led the Chargers offense to 17 points after halftime. He'll likely play against Tampa Bay on Sunday even if he's not 100 percent healthy, although Taylor Heinicke and Easton Stick are taking extra reps in practice at the start of the week.

Raiders head coach Antonio Pierce said that O'Connell (knee) is in line to participate in Wednesday's walk-through practice, Paul Gutierrez of ESPN.com reports.

Though O'Connell's presence on the field in any capacity three days after suffering a bone bruise in his left knee in Sunday's loss to the Buccaneers is a positive indicator, Pierce wouldn't commit to the quarterback being available for the Raiders' Week 15 matchup with the Falcons on Monday night. Pierce noted that how O'Connell looks in practice this week will be the deciding factor in whether he starts this week, and if the second-year signal-caller isn't available to play, the Raiders would turn to Desmond Ridder to direct the offense.

Giants head coach Brian Daboll said Wednesday that Lock is tending to a heel injury and is likely to cede starting quarterback duties to Tommy DeVito in Sunday's game against the Ravens, Dan Salomone of the Giants' official site reports.

Lock is in a walking boot and won't practice Wednesday, leaving DeVito to take all of the first-team reps as he prepares for what would be his second start of the season Sunday. When New York waived Daniel Jones in November, DeVito received the first chance to step in as the Giants' starter in a Week 12 loss to Tampa Bay, but DeVito suffered a forearm injury in that contest, which opened the door for Lock to start the past two games. Though Daboll said Monday that Lock would remain the starting quarterback if healthy, the 28-year-old looks like he'll have to miss at least one game after emerging from this past Sunday's 14-11 loss to the Saints with the heel issue. The Giants haven't yet discounted Lock from being available for the Week 15 contest, but assuming he's formally ruled out following the release of Friday's injury report, Tim Boyle likely will be elevated from the practice squad to serve as DeVito's backup against Baltimore.

Giants head coach Brian Daboll said that DeVito is expected to start Sunday's game against the Ravens, Jordan Raanan of ESPN.com reports.

Just two days ago, Daboll noted that Drew Lock would remain the team's starting quarterback if healthy, but the signal-caller is tending to a heel injury that has confined him to a walking boot and will prevent him from practicing Wednesday. While Daboll hasn't officially ruled out Lock for being available as an emergency backup Sunday, the Giants will turn the starting role back over to DeVito, who previously directed the offense in a Week 12 loss to the Buccaneers after incumbent Daniel Jones was cut. While DeVito had a few good moments over his six starts in 2023, he faded down the stretch last season and struggled to move the offense in the 30-7 loss to Tampa Bay, completing 21 of 31 pass attempts for 189 yards, no touchdowns and no interceptions to go with 32 yards on seven carries. Though DeVito brings above-average rushing ability at quarterback, his substandard skills as a passer make him a low-end fantasy option in Week 15, especially now that every team has already had its bye week.

Bagent played four snaps and completed his lone pass attempt for a six-yard gain in Sunday's 38-13 loss to the 49ers.

The second-year quarterback made his third appearance of the season Sunday, with all having come at the tail end of blowout wins or losses with starter Caleb Williams having thus far enjoyed good health during his rookie campaign. Even with the 4-9 Bears on the cusp of being eliminated from playoff contention, don't expect Bagent to get any starts over the final four contests while Chicago remains committed to Williams as its present and long-term solution under center.

Boyle signed to the Giants' practice squad Tuesday, Dan Salomone of the Giants' official site reports.

Boyle signed to the Giants' practice squad in November before moving up to the active roster to serve as the third quarterback behind Tommy DeVito and Drew Lock. Boyle was waived on Saturday ahead of New York's 14-11 loss to the Saints on Sunday, but Lock needed X-rays for an undisclosed injury after the defeat. New York coach Brian Daboll said Lock would remain the starter if he's healthy enough to go next Sunday against the Ravens, per Art Stapleton of The Bergen Record.

DiNucci signed to the Saints' practice squad Tuesday, Mike Triplett of NewOrleans.Football reports.

The quarterback was waived by the Bills in August after trying to win the third QB job behind Josh Allen and Mitchell Trubisky. DiNucci spent 2023 on Denver's practice squad but did not appear in a regular-season game. New Orleans starter Derek Carr is week-to-week with a hand fracture, but he also has two healthy backups in Jake Haener and Spencer Rattler.

Head coach Raheem Morris said Monday that Penix will remain the backup to starting quarterback Kirk Cousins for Week 15, Terrin Waack of the team's official site reports. "Kirk is our quarterback. Kirk is still going to lead us," Morris said.

Atlanta has dropped four straight games to fall out of the lead in the NFC South at 6-7, and Cousins' struggles have led to a discussion about a change under center. In those four losses, the veteran QB completed just 62.4 percent of his passes for 7.6 yards per attempt and a 0:8 TD:INT while also taking eight sacks. Cousins' track record and sizable contract may not be enough to save him if he has another poor showing against a reeling Raiders squad Monday. Penix, the eighth overall pick in April's draft, has made just two brief mop-up appearances through the first 14 weeks of the regular season but looked composed during his lone preseason outing, completing nine of 16 pass attempts for 104 yards.

The Raiders signed Luton (shoulder) to the practice squad Tuesday.

Luton spent the offseason with Carolina, but he was cut from IR with an injury settlement by the Panthers prior to Week 1. Now, Luton appears fully recovered from his shoulder issue and will be available to provide emergency quarterback depth for Las Vegas, with starter Aidan O'Connell (knee) looking uncertain for Week 15.

The Raiders signed Bradley to the 53-man roster from the practice squad Tuesday.

Bradley, who was previously elevated Week 8 against Kansas City but didn't play, looks like he'll get a chance to handle a reserve role for Las Vegas during Monday's game against the Falcons. The health of starter Aidan O'Connell (knee) remains uncertain for Week 15, so it's possible Bradley could be called upon to handle the backup role behind Desmond Ridder.
