Englewood, Colo. • C.J. Anderson is seeking a second opinion on his injured right knee 48 hours after his best performance of the season sparked Denver's 27-9 win over the Houston Texans.

The Broncos are unsure how long he might be out.

Anderson, who signed a four-year, $18 million contract in the offseason, bruised his right knee on his final carry of the first quarter Monday night, an 11-yard run.

He returned to the game, however, and ran 14 more times for 84 yards, finishing with a season-best 107 yards on 16 carries.

Coach Gary Kubiak said Anderson was sore Tuesday and went for medical tests. He missed Wednesday's practice to seek a second opinion.
