Houston Texans running back Arian Foster was forced from Houston's Week 5 game against the Indianapolis Colts with a potential concussion.
After the hit, Foster actually came back in for the remainder of the series -- carrying the ball once -- before the training staff took his helmet away. He went back to the training room for further evaluation.
This is just his second game back from a groin injury. Prior to the injury, Foster had already racked up 15 touches, but he'd only mustered 36 total yards with the heavy volume.
