It was the second career touch for the third-round pick out of Kansas State. Lockett had a 103-yard kickoff return and 67-yard punt return for touchdown in the preseason.

Rams special teams ace Chase Reynolds injured his knee on the play. Reynolds was hit twice at the line near the end zone and could only hobble while Lockett sped by.

Bills safety Corey Graham has been escorted off the field after being kneed in the helmet while tackling Indianapolis running back Frank Gore on the first play from scrimmage.

Graham was being examined for a possible concussion. Gore took a pitch to the left and was turning the corner, when Graham came sliding in and tripped up the running back. Gore's left knee struck Graham directly in the helmet.

Graham was wobbly as he attempted to get up, and then nearly collapsed. The team said he would not return to the game.

The injury further depletes the Bills secondary, which is already minus starting cornerback Leodis McKelvin, who's still recovering from a broken right ankle.

Outside linebacker Jadeveon Clowney - the league's top pick in 2013 - is finally back on the field with the Houston Texans.

Clowney played on Sunday for the first time since microfracture surgery in December.

Clowney was a dominant college defender at South Carolina, but played just four games as a rookie because of various injuries. He didn't start Sunday, but came in on the second play against Kansas City.

He was in for three plays before leaving the game for a couple of plays. He returned and helped pressure Alex Smith into an incomplete pass on third down to force a punt.
