The Los Angeles Rams' hopes of achieving a first-round bye in the playoffs this season took a hit in more ways than during their Week 15 game against the Philadelphia Eagles.

Not only did the Rams surprisingly lose their game on Sunday night against the Eagles, who were without Carson Wentz, their star running back Todd Gurley also picked up an injury during the contest.

Gurley was sidelined for a series in the third quarter of Sunday night's 30-23 loss to Philadelphia as he injured his left knee during a play.

The running back was able to return to the game, and he finished with 48 rushing yards and two touchdowns on 12 carries and caught 10 passes for 76 yards.

After the game, Gurley said he was fine since he was able to return, but Rams head coach Sean McVay has said his running back is day-to-day ahead of their Week 16 game.

He said, according to ESPN: "If he's able to go, we want him to be able to go. But if it's something that whether you're playing for the playoffs or whether you're not, we're always going to be smart with a player like Todd."

Although a playoff berth has been secured, the Rams would like to have Gurley on the field in order to try and secure a first-round bye in the playoffs in order to give him and the rest of the team a rest ahead of a Super Bowl push.

Gurley currently ranks second in the NFL with 89.4 rushing yards per game and has scored a league-high 21 touchdowns.

However, if he is unable to play this weekend against the Arizona Cardinals, third-string John Kelly will likely take his place in the backfield, as the backup running back Justin Davis is dealing with a shoulder injury and is also day-to-day.

Sitting on a 11-3 record, the Rams need to win their final games of the regular season against the Cardinals and the San Francisco 49ers in order to lock up a first-round bye in the postseason.
