Detroit Lions safety Glover Quin is being evaluated for a concussion and has been ruled out of Sunday's game against the New Orleans Saints. Quin was injured trying to tackle Saints running back Alvin Kamara on a first-and-10 from the New Orleans 46-yard-line. When Quin was trying to tackle Kamara, teammate A'Shawn Robinson's knee appeared to collide with his helmet. Quin immediately fell to the ground and didn't appear to be moving for a short period of time.
