Spiller hurt early, but Bills say he's 'OK'

Buffalo Bills running back C.J. Spiller appeared to injure his right knee in the first quarter of Saturday's preseason game against the Washington Redskins.

Spiller fell hard on his right knee as he scored on a 2-yard touchdown run on the Bills' second offensive drive. Lying on his back in the end zone, Spiller immediately grabbed his knee before asking teammates to help him to his feet. Spiller then took a few steps, limping, before a trainer assisted him back to the ground.

Soon after, Spiller walked to the sideline under his own power and appeared to be moving well. The Bills quickly tweeted that their running back was "OK."

Before the injury, Spiller had rushed five times for 30 yards, including a 19-yard scamper before his touchdown run. ESPN's Adam Schefter tweeted that Spiller's knee was cut by a spike. Spiller re-entered the game early in the second quarter.
