Tyler Eifert underwent back surgery on Tuesday.

Eifert was put on IR this week after playing in only eight games because of ankle and back injuries.

Eifert caught 29 balls for 394 yards and five touchdowns over eight games this season for the Cincinnati Bengals.

Tyrod Taylor will be seen by Dr. William Meyers for a severe groin injury to determine if he needs surgery.

If that happens to Taylor, the clock will begin to tick on whether he can pass a physical before the third day of the 2017 league year.

The procedure could cost the Bills $30.5 million in guaranteed money to Taylor, who the franchise appears to prefer to move on from.

Derek Carr underwent successful surgery on Tuesday and while there's no official timeline for his return, he could conceivably be football ready in six to eight weeks.

With that timetable, Carr could be ready in some capacity for the Super Bowl if the Oakland Raiders were to advance.

Matt McGloin will start for the Raiders in the absence of Carr.

The Raiders can clinch the AFC West title and a first-round bye with either a win at Denver on Sunday or a Kansas City loss in San Diego. If the Raiders lose and the Chiefs win, Oakland will open the playoffs at AFC South champion Houston on wild-card weekend.

"We're up for the challenge," Latavius Murray said. "I know Matt is. We're not going to change anything. We're going to go out and execute and do what we do."

Tyler Lockett suffered a broken leg and will require surgery.

Lockett initially appeared to score a touchdown on the play but was ruled down just short of the end zone.

A defensive back of the Cardinals rolled up on his knee which appeared to snap just below his knee.

Coming into Saturday’s game, Lockett was the team’s third leading receiver behind Doug Baldwin and Jimmy Graham.

Terrell Suggs insists he'll return for his 15th NFL season in 2017.

Suggs will turn 35 next season and seemed insulted with the question of a possible retirement.

"I don't know what you heard -- what the [f---] is wrong with him?-- I was always planning to come back and doing this another year," Suggs said.

Suggs leads the Ravens with eight sacks this season, despite playing with a torn biceps in his left arm since Oct. 16. 

Carlos Hyde suffered a torn MCL in the 49ers' Week 16 win over the Rams.

Hyde suffered the injury when he was hit in the left leg on a carry. Hyde walked off the field under his own power but did not return.

"It didn't feel that bad when it first happened. It's pain, there's some pain, but it didn't feel like bad pain. I've felt worse," Hyde said after Saturday's win. "That's why I was able to get up and walk off on my own."

Hyde nearly rushed for 1,000 yards this season to go with six touchdowns.

Marcus Mariota suffered a fractured right fibula and will miss the rest of the season.

Mariota was carted off in the third quarter with an air cast on his right leg after being sacked from behind by Jaguars DT Sheldon Day.

"We didn't protect him -- offensive line, running backs -- we didn't protect him all day," Titans RB DeMarco Murray said after the game.

Matt Cassel will assume the starting quarterback job for the Tennessee Titans.

Derek Carr suffered a broken right fibula while getting sacked early in the fourth quarter Saturday and is out indefinitely.

Carr will undergo surgery on Sunday and the Oakland Raiders will start Matt McGloin at quarterback.

"It obviously is a blow," Jack Del Rio said. "That's what teams do; teams have to find a way to pick up and move on. We'll rally around the next guy as best we can. That's what you do.

"It will be incumbent on the offensive line and the backs to do more. The defense to do more. The special teams to do more. As a team, pick it up and do more to fill in. Obviously, it's a big setback."

In obvious pain, Carr appeared to mouth, "It's broken," as team medical personnel attended to him.

Carr, 25, could not put any weight on his right foot and had to be helped to the sideline.

Adrian Peterson has been ruled out for Week 16 for the Minnesota Vikings against the Green Bay Packers.

Peterson returned for Week 15 from his meniscus surgery and rushed six times for 22 yards.

Peterson had said earlier this month he would only play if the Vikings were in playoff contention, adding it would be "pointless" to play if the Vikings weren't able to make the playoffs. 

Peterson, who turns 32 in March, is on a team option for the 2017 season that includes a $6 million roster bonus on the third day of the league year. Peterson would carry an $18 million cap figure in 2017, and it seems likely the Vikings would pursue a restructured contract with the three-time NFL rushing leader, rather than picking up the option as it currently exists.

Ryan Mathews suffered a herniated disk in Week 16 and will miss the Philadelphia Eagles' Week 17 finale against the Dallas Cowboys.

The Eagles are mathematically eliminated, while the Cowboys have clinched home-field advantage throughout the NFC playoffs. 

Mathews rushed for 661 yards on 155 carries and eight touchdowns in 2016.
