Oakland Raiders running back Rashad Jennings left Thursday’s game against the Dallas Cowboys after taking a knee to the helmet and the Raiders reported that Jennings sustained a concussion on the play.
According to Pro Football Talk, the official diagnosis means Jennings now falls under the league’s concussion recovery protocols. He can’t practice or play until he is cleared by an independent neurologist.
The Raiders have 10 days before their next game, Dec. 8 at the New York Jets.
Jennings had gained 553 yards from scrimmage in Oakland’s last four games, but was held to 35 yards on 17 carries on Thursday, although he did score two touchdowns.
If Jennings isn’t cleared to play on Dec. 8, the assumption is that Darren McFadden would move back to the top of the depth chart. McFadden lost the job to Jennings after injuring his hamstring on Nov. 3.
