But matching up with Mario Manningham, Allen was in pursuit on a seven-yard catch by the Giants' Rashad Jennings and collided with Davis. After huddling with his teammates for the next play, Allen slowly bent down, falling backward. He was then tended to by a team trainer and walked off the field under his own power, although he did not return. The team later announced that Allen was out with a head injury and later a concussion.
