McCoy described it as a "sharp pain" after his leg gave out. He said it might have been a cramp.
"It just grabbed really tight," McCoy said. "I was cutting and running, and it kind of just gave out. But I went back there and did some stretching and different treatment and I was back."
Cole collided with Chung while in coverage in the fourth quarter. He was evaluated for a concussion and cleared to return.
"I just got my brain switched around a little bit," Cole said.
Chung left with a throat injury in the first quarter. He also bit his tongue.
Foles said he "banged up" his shoulder on a hit in the second quarter. He spent the remainder of the drive winding his right arm between plays. It appeared that he was in discomfort, but Foles said he was doing it to keep his arm loose.
"I had a shoulder injury in high school, and I knew the key when you get banged up is to keep it warm," Foles said. ". . . I didn't want it to get tight."
Foles said he had no problem throwing the rest of the game.
