Tight end Jordan Reed suffered a quad contusion after taking a helmet to the leg in Sunday’s 27-20 loss to the Detroit Lions at FedEx Field.

Reed had taken over as the team’s primary pass-catching tight end with Fred Davis sidelined by a sprained ankle, and but left the game in the second half with an injury of his own.

“It’s real frustrating I couldn’t keep playing,” Reed said in the locker room after the game. “I’ve got to come in [Monday] and see what kind of treatment I need.”

Reed had five catches for 50 yards on six targets.

Reed was the second player to leave the game with injury. Rookie linebacker Brandon Jenkins sprained his right ankle and didn’t return. Jenkins plays primarily in special blitz packages. Redskins coach Mike Shanahan said after the game that he yet didn’t know how serious Jenkins’ injury was.

Meanwhile, Shanahan provided insight into the injury that caused the team to add Davis to the injury report on Saturday.

Davis rolled his ankle on the last play of Friday’s practice, Shanahan said, and woke up Saturday morning experiencing some soreness and swelling. The Redskins listed Davis as questionable on Saturday.

He tried to test out his ankle prior to Sunday’s game, but moved gingerly even while walking.
