New England Patriots cornerback Stephon Gilmore, the reigning NFL Defensive Player of the Year, left Sunday's game against the Miami Dolphins late in the second quarter with what appeared to be a serious knee injury.
Gilmore planted on the natural grass surface at Miami's Hard Rock Stadium while backpedaling, and his right leg gave out on him. The noncontact injury, which occurred away from the play, led to Gilmore being helped to the locker room. He was not able to put pressure on his right leg.
The Patriots officially ruled Gilmore out for the game in the second half.
