The Atlanta Falcons might be without versatile quarterback Michael Vick after he sprained his right shoulder in a a 20-6 loss to Tampa Bay on Sunday.

Vick injured his non-throwing shoulder two minutes into the third quarter, when he was sacked by Simeon Rice. After Warren Sapp forced him from the pocket, Vick was driven to the turf by Rice and came down hard on his right shoulder.

X-rays were negative, but the 22-year-old quarterback wasn’t sure if he would be able to play against the New York Giants on Sunday.

“It’s really sore right now,” he said. “I can’t really lift my arm up. I’ve never really been hit like that before, where a guy falls on top of me. And I’ve never really had any problems with my shoulder. So I knew something was definitely wrong.”
