JJ Watt has said that he expects a "good challenge" when he lines up against Chance Warmack at the weekend.

The 2012 defensive player of the year will face the Tennessee Titans' first-round Draft pick when the team travel to the Houston Texans on Sunday.

The Texans defensive end told reporters: "Yesterday afternoon and today have really been my first chance to watch the film on the Titans. I'm early on my film work, but obviously he's a good young player and it's going to be a good game.

"I can just go off the film I watch and the film I have of him in the league. He's strong. He's a good football player. I assume from the tradition at Alabama that he's got good technique, that he's had good coaching for four years now.

"Like I said, to obviously be a first-round pick in the NFL you have to be a good football player. It'll be a good challenge."

Both teams won their opening games of the season.
