J.J. Watt plays 96 percent of the Texans' snaps, but he left the field midway through the 3rd quarter with what the team is calling a groin injury. He returned a short time later, and on the first play back he was manhandled by embattled Chiefs tackle (and former No. 1 overall pick) Eric Fisher. Of course, Watt appeared a step slow and hobbled, which is one of the few ways Fisher would have a chance against one of the NFL's best players.

The Houston Chronicle's John McClain reports that fans were booing Fisher for the play, though in his defense, he didn't know Watt was hurt. Watt had to be helped off the field, and the Chiefs scored a few plays later to take a 20-0 lead.

And while Watt's fate for the rest of the game is unclear (he's listed as questionable), it may already be too late, thanks in large part to Brian Hoyer's four-turnover first-half performance.
