Teddy Bridgewater suffers concussion on elbow to head, ruled out vs. Rams

— -- MINNEAPOLIS -- Vikings quarterback Teddy Bridgewater was diagnosed with a concussion after being elbowed in the head by Rams defensive back Lamarcus Joyner in the fourth quarter of Minnesota's 21-18 victory.

Bridgewater suffered the injury while sliding for a five-yard gain with 13:36 left in the fourth quarter. He remained facedown on the field for several seconds after the hit from Joyner, who came in after Bridgewater had already begun his slide.

The quarterback had taken a low hit from William Hayes on the Vikings' previous drive, but referee Ron Torbert didn't call a penalty with Bridgewater outside the pocket. After the Joyner play, Vikings coach Mike Zimmer ran out onto the field to scream at officials for the hit.

Bridgewater ran to the locker room with trainers as Vikings backup quarterback Shaun Hill came in to face his former team in the fourth quarter.

Before the hit, Bridgewater was 13-for-21 for 144 yards and an interception, and had carried three times for 17 yards and a touchdown. He'd also run for a two-point conversion, giving the Vikings an 18-15 lead over the Rams.

Rams defensive coordinator Gregg Williams has a history with the Vikings; he was the New Orleans Saints' defensive coordinator in 2010, when the Saints' bounty system targeting quarterback Brett Favre became national news after New Orleans beat the Vikings in the NFC Championship Game.
