49ers running back Marcus Lattimore said he's retiring from football because he's been unable to get his knee "fully back to the level the NFL demands." Lattimore suffered serious knee injuries in 2011 and 2012 while playing for South Carolina.
Eagles linebacker Emmanuel Achowas ruled out for the remainder of the game with a groin injury, the team announced shortly after the start of the second half. Acho sustained the injury in the second quarter, shortly after getting beat by Delanie Walker. He finished the game without a tackle.
