The Houston Texans aren't sure when Jadeveon Clowney plans to report to training camp.

"I don't know. I really don't," Bill O'Brien said when asked. "I know he's working hard. He's out there working out ... he's in shape. He's doing everything he needs to do to be ready to play. But ultimately that's up to him (when he reports). When he wants to show up, he'll show up, and he'll be ready to go. He's a professional. When that happens, we'll move forward with that. But I have no idea when he'll be here. I can't predict that."

It has previously been reported that Clowney would report after the third preseason game.
