Giants head coach Brian Daboll said Monday that Lock (undisclosed) is undergoing an MRI but remains in line to start Sunday's game against the Ravens, as long as he's able to suit up, Art Stapleton of The Bergen Record reports.

Lock was sent for X-rays after New York's 14-11 loss to the Saints in Week 14, a contest in which he completed just 21 of 49 passes for 227 yards and an interception. He did, though, toss a two-point conversion and add 59 rushing yards on five carries. Daboll said Lock emerged from the loss with "a couple bumps and bruises," per Charlotte Carroll of The Athletic, so there seems to be optimism that he's avoided a more serious injury.

Coach Antonio Pierce said after Sunday's 28-13 loss to the Buccaneers that O'Connell's knee injury "doesn't look good," per Vic Tafur of The Athletic, and Ian Rapoport of NFL Network reports that O'Connell is set to undergo additional testing Monday.

O'Connell needed an air cast on his left leg immediately after getting hurt against the Buccaneers and was carted off the field. While official word on the severity of the injury won't come until after the results of Monday's MRI, it's likely that O'Connell's injury will keep him from suiting up for the Raiders' remaining four games, which would thrust Desmond Ridder into a starting role.

Herbert completed 21 of his 30 pass attempts for 213 passing yards and a touchdown in the 19-17 loss to the Chiefs on Sunday. He also carried the ball four times for 12 yards.

Despite entering the game without his favorite target in Ladd McConkey (knee/shoulder) and losing another in Will Dissly (shoulder) during the contest, Herbert played well enough despite the hostile conditions. The Pro Bowl quarterback sprinkled the ball around to eight different targets and completed more than 20 passes for just the second time in the last six contests. He also left the game briefly after taking a big hit to his lower body, but the 26-year-old was able to return after missing just one play. Coach Jim Harbaugh clarified after the game that Herbert was dealing with a leg contusion, per Daniel Popper of The Athletic. The status of McConkey will be worth monitoring given Los Angeles' next opponent is the porous Tampa Bay pass defense, and should the rookie play, Herbert could be poised for a solid fantasy day.

Mahomes completed 24 of 37 passes for 210 yards and one touchdown in Sunday's 19-17 win over the Chargers. He added four rushing attempts for 17 yards.

Mahomes put the Chiefs up 13-0 with a nine-yard touchdown pass to DeAndre Hopkins in the final minute of the first half, but the Chargers scored 14 unanswered points in the third quarter. The two teams then exchanged go-ahead field goals in the fourth quarter before Mahomes converted a pair of third downs with passes of 14 yards to Xavier Worthy and nine yards to Travis Kelce to set up Matthew Wright's game-winning 31-yard field goal on the game's final play. It hasn't always been pretty offensively as Kansas City navigates subpar offensive line play with a depleted receiving corps, but Mahomes has led the Chiefs to a 12-1 record and an AFC West Division title heading into a Week 15 trip to Cleveland.

Haener did not attempt a pass but logged one carry on a kneel-down play during Sunday's 14-11 win against the Giants.

Haener took the reins after starting quarterback Derek Carr (hand/head) got injured on a rushing attempt late in the fourth quarter. The second-year backup wound up playing just a handful of snaps, taking a sack and handing the ball off three times before lining up in victory formation on the final play of the game. Carr was removed for a concussion evaluation to go along with a hand injury, and reports following the game indicated that he's feared to have suffered a fractured left hand, according to Ian Rapoport of NFL Network. If that's the case, then Carr availability for the remainder of year would certainly be up in the air, leaving Haener as the likely candidate to step in as the new QB1 since rookie signal-caller Spencer Rattler was ruled a healthy scratch Week 14. The Saints will next play versus the Commanders on Sunday, Dec. 15.

Ridder entered Sunday's 28-13 loss to the Buccaneers for Aidan O'Connell (knee) with 14:03 remaining in the fourth quarter and completed 12 of 18 passes for 101 yards with no touchdowns or interceptions. He also rushed twice for three yards and fumbled once but recovered.

Ridder had most recently seen playing time in Week 12 against the Chiefs, so rust wasn't an issue for the third-year pro. Ridder was able to lead the Raiders to three points on his second possession, although he did see a would-be interception reversed on replay during the drive. Considering O'Connell's injured leg was placed in an air cast and the second-year signal-caller was carted off Sunday, Ridder appears to have a good chance of drawing a start against his former Falcons squad in a Week 15 home matchup Monday night, Dec. 16.

Stafford completed 23 of 30 passes for 320 yards, two touchdowns and no interceptions in Sunday's 44-42 win over the Bills.

Despite the score and the stat line of Josh Allen, the Rams prioritized their running game. That limited Stafford's passing volume, but he made up for that by averaging 10.7 yards per attempt while completing four passes of more than 20 yards. He also found the end zone on passes of 17 and 19 yards to Puka Nacua and Cooper Kupp, respectively. Stafford now has multiple scores in four straight games with no interceptions, though this was his first 300-yard performance since Week 1.

Purdy completed 20 of 25 pass attempts for 325 yards and a pair of touchdowns while rushing five times for 11 yards in Sunday's 38-13 win over the Bears.

Purdy did suffer an injury scare in the fourth quarter on a roughing the passer penalty that saw the quarterback's body bend backward in an awkward fashion between two Chicago defenders. The star QB was writhing in pain on the ground following the hit, but he wound up missing just one play before returning to the field, as reported by 49ers' reporter Cam Inman. Aside from the brief injury scare, Purdy was firing on all cylinders against the scuttling Bears, which comes as a relief to fantasy managers following last week's dud against the Bills in the snow. Assuming that there are no lingering effects from getting clotheslined Sunday, Purdy could be in store for another high score in a potential shootout against the Rams on Thursday Night Football in Week 15.

Murray completed 25 of 38 passes for 259 yards, two touchdowns and two interceptions in Sunday's 30-18 loss to the Seahawks. He added three rushing attempts for 16 yards and ran in a two-point conversion.

Murray threw a 41-yard touchdown pass to Michael Wilson on the opening drive, but the quarterback was picked off on the next two possessions, which helped Seattle build a 24-10 halftime lead. Murray closed the gap to 27-18 in the third quarter with a two-yard touchdown pass to James Conner followed by a Murray rush for a two-point conversion, but that's as close as Arizona would get. While Murray tossed multiple touchdown passes for only the third time this season, he also finished with multiple interceptions for the second consecutive game after having no multi-interception games through Week 12. He'll look to clean up the mistakes in Week 15 against the Patriots.

Williams completed 17 of 23 pass attempts for 134 yards and two touchdowns while rushing four times for 27 yards with a fumble in Sunday's 38-13 defeat to San Francisco.

Williams and Chicago's offense were nearly invisible Sunday, netting just four yards over five drives (all of which ended in a punt) in the first half. The first-overall pick from this year's draft was able to pad his stats out of the break with a pair of touchdown throws that never threatened the 49ers' lead. On the bright side, Williams has now thrown seven touchdowns over his last three contests after failing to generate one over his previous four appearances. Things won't get any easier for the Bears as they prepare to visit the Vikings next Monday.
