Texans rookie Jadeveon Clowney exited practice Saturday, dealing with what appeared to be a right leg injury. The No. 1 overall pick of the 2014 NFL draft was active from 8 a.m. until about 10, when he moved toward the trainer’s table. Clowney lifted his right leg several times and ice was applied. He eventually left practice on a cart. “We’re just trying to manage him,” coach Bill O’Brien said at NRG Stadium. “He’s coming off of surgery and we’re just trying to manage him. He’s out there and he wants to go every rep. And I’m sure just like all the guys, after seven practices I’m sure he’s a little sore and we’ll just continue to manage him.”
