Arizona Cardinals running back James Conner left with a knee injury and did not return for his team’s 13-9 loss to the Los Angeles Rams on Saturday.

Conner was seen being examined in the second quarter of Saturday’s competition before jumping on a stationary bike to try to work out his knee.

The running back managed four yards on four carries before heading to the sideline. He also caught two passes for four yards.

It wasn’t a given that Conner would play this week after recovering from a knee injury suffered in last week’s overtime loss to the Carolina Panthers. Despite only playing about three quarters, Conner managed to improve Carolina’s run defense with 117 yards and a touchdown on 15 carries. He also topped all Arizona pass catchers with 49 yards on four receptions.

But after a week of limited practice, Conner was deemed healthy enough to play this week.

With both Conner and rookie Trey Benson out due to injuries, Arizona turned to running back Michael Carter to fill the void. He finished the game with 70 yards on 13 carries and two catches for 11 yards.

In addition to Conner, cornerback Garrett Williams also missed time after being placed in the concussion protocol but eventually returned to action.
