HOUSTON (AP) -- The Houston Texans see J.J. Watt make disruptive plays in practice all the time.

The 6-foot-5, 288-pound rookie defensive end is constantly swatting passes, and even intercepting a few. He finally hung onto one when it counted, in the biggest game of the year.

Watt's game-changing interception return for a touchdown on Saturday propelled the Texans (11-6) to a 31-10 win over Cincinnati and set up a matchup with Baltimore (12-4) in the next round of the playoffs.

The 10-year-old Texans won their first playoff game, and now have the daunting task of facing Ray Lewis and the Ravens on their home field. Baltimore is 8-0 at M&T Bank Stadium this season, including a 29-14 win over Houston in Week 6.
