Conner will miss at least the Cardinals' next four games while on IR.
The injury happened on Conner's 35-yard run in the second quarter. After the game, Cardinals coach Jonathan Gannon said Conner's foot might have gotten stuck in the ground when he twisted his knee. Conner went to the locker room after suffering the injury, then returned to the sideline in full uniform but didn't play another down. He was replaced by rookie Emari Demercado. Conner had 46 yards on six carries before the injury.
Conner's injury was another blow to the Cardinals' running back depth chart. His backup, second-year running back Keaontay Ingram, has been inactive the past two games with a neck injury. The depth chart also includes Demercado and practice squad running back Corey Clement, who's been elevated the past two games.
"He's just a guy that we felt could possibly help us," Gannon said of Jones. "He's an instinctive guy and powerful -- a good player."
