Texans' J.J. Watt: Limited participation Friday, will start Sunday

Watt (back) was limited at Friday's practice.

Analysis:

Watt went from full participation Wednesday to limited the next two days, but "he had a good week of practice and he'll be ready to go," head coach Bill O'Brien told the Houston Chronicle. Watt, who is coming back from offseason surgery to repair a herniated disc, played 88 percent of the defensive snaps in Week 1.
