Injury roundup: Jadeveon Clowney reportedly tears meniscus

Houston Texans rookie linebacker Jadeveon Clowney limped off the field and headed to the locker room in the second quarter Sunday against the Redskins.

The early prognosis was thought to be "good," head coach Bill O’Brien said in the postgame news conference, but since then multiple reports indicate the injury is more severe.

Clowney, who underwent sports hernia surgery and suffered a concussion earlier this preseason, was reportedly "visibly upset" while being escorted by a trainer into the locker room.
