Montee Ball has said that the Denver Broncos must be aware of JJ Watt when they face the Houston Texans later today.
Last season's defensive player of the year has made 55 tackles, 9.5 sacks and forced three fumbles so far this season.
The Broncos running back, who was a teammate of Watt in college, told reporters: "He's just that dominant.
"But for us we just have to focus on what we can control, which is executing, establishing the run game and, obviously, putting the ball in the air. But we're going to have an eye on him on defense."
The Broncos head into the game on the back of their third defeat of the season.
