Watt had a procedure in January to repair his core-area muscles. He played through a broken hand and herniated disk last season.

The three-time defensive player of the year, hasn't missed a game during his illustrious five-year career. His 17.5 sacks last season led the league, the second time he's accomplished that feat.

The four-time Pro Bowl defensive end has had double-digit sack totals each of the past four seasons, racking up 74.5 for his career. He signed a six-year, $100 million extension with the Texans in 2014.

The Texans are hoping to make a deep run in the playoffs this season after losing in the wild-card round last year against the Chiefs. Houston is coming off back-to-back 9-7 seasons and signed what it hopes is its franchise quarterback, locking up former Broncos QB Brock Osweiler to a four-year, $72 million contract.
