A person with knowledge of the situation tells The Associated Press that Broncos linebacker Von Miller's season is over after tests revealed a torn anterior cruciate ligament in his left knee.
The person spoke on the condition of anonymity because coach John Fox had not yet addressed the media at his regular Monday news conference.
Miller was injured in the first quarter of Denver's 37-13 win at Houston on Sunday.
The injury ended a rough third season for the Broncos star, which began with a six-game drug suspension and finished with just five sacks in 10 games.
He had 30 sacks in his first two NFL seasons
