Lions' Bentley leaves after 2nd-quarter collision
Bentley was trying unsuccessfully to prevent a touchdown pass to Jerrel Jernigan when Detroit teammate Louis Delmas appeared to catch him in the head with his arm. Bentley was down for a while, but he was able to walk off the field with some assistance. He will not return to the game.
Detroit tackle LaAdrian Waddle went down with an ankle injury in the second half.
