Read about the rest of Thursday's injury news:
- Robert Griffin III went to the ground in an attempt to recover his own fumble and was landed on by mutliple Lions defenders early in the second quarter of a 21-17 victory. Griffin was down for three minutes as he was tended to by team trainers before walking off the field under his own power. After the game, coach Jay Gruden said Griffin suffered a concussion and would undergo concussion protocol. He also described the quarterback's shoulder as "OK."
