The Cardinals are treating Drake’s injury like a high-ankle sprain, the source said. X-rays taken Sunday night were negative.
Drake suffered the injury with 4 minutes, 12 seconds left in the fourth quarter of the Cardinals’ 37-34 overtime victory over the Seattle Seahawks. He was carted to the locker room with a towel over his head. He had 34 yards on 14 carries plus one catch for 7 yards.
Drake, who is playing this season on a transition tender worth $8.483 million, leads the Cardinals with 512 rushing yards and has scored four rushing touchdowns this season.
