Woodhead, a free-agent pickup this year, was key on Baltimore's opening drive. He caught three passes for 33 yards (picking up first downs on each one) and ran the ball once for four yards.
But, on the last play of the drive, Woodhead held his hamstring as he fell to the ground. He was helped to the sideline by trainers and was declared doubtful for the rest of the game.
"We'll see," Woodhead said about the severity of his injury. "It's one of those things ... we'll wait until we get back."
Woodhead missed the last two preseason games with a hamstring injury. His season ended last year with a torn ACL.
"I'm going to wait and see what we got," Woodhead said when asked if this was the same hamstring that kept him out the two preseason games.
The injury to Woodhead left the Ravens with two healthy running backs: Terrance West and Buck Allen.
