As rookie outside linebacker Jadeveon Clowney recovers from sports hernia surgery, another important Houston Texans defensive player is sidelined.

Texans defensive end J.J. Watt, the 2012 NFL Defensive Player of the Year, is sidelined with a hyperextended knee.

He got hurt Thursday and didn't practice Friday.

The injury isn't regarded as a long-term ailment.

“He’s fine,” Texans coach Bill O’Brien said. “It’s not serious at all. We just gave him the day off.”
