Los Angeles Rams star Todd Gurley is "day-to-day" with knee inflammation, head coach Sean McVay told reporters on Monday.
Rams running back Gurley originally suffered the injury in the third quarter of Los Angeles' 30-23 loss to NFL Super Bowl champions the Philadelphia Eagles on Sunday, but he returned after missing one series.
Gurley rushed for 48 yards and two touchdowns on 12 carries against Philadelphia. He also caught 10 passes for 76 yards.
"I returned, so I was fine," Gurley said about the injury on Sunday.
The Rams have already clinched a spot in the playoffs. McVay did not commit to Gurley playing in the team's week-16 matchup against the lowly Arizona Cardinals.
"If he's able to go, we want him to be able to go," McVay said. "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."
Gurley – a two-time Pro Bowl player – has tallied 1,251 yards and 17 scores on the ground in 2018. He has also added four receiving touchdowns.
The Rams will enter their matchup in Arizona with an 11-3 record but on a two-game losing streak.
