Bills receiver Stevie Johnson limped off the field after breaking the huddle and was looked at by trainers on the sideline.
He returned later in the drive. However, he was limping on the field and seemed to be struggling with a hip or groin problem. He left the field and was seen stretching.
Bills cornerback Leodis McKelvin left the field late in the first quarter with what looked like a shoulder injury but returned to return a punt in the second quarter.
He was seen rotating the shoulder for trainers on the field before going to the sidelines and removing his helmet. He was replaced for about a quarter by Ron Brooks in the secondary.
