Denver Broncos linebacker Danny Trevathan will miss four to eight weeks after fracturing his knee, he told ESPN's Josina Anderson.

Trevathan told Anderson that the doctor said his ACL and MCL are "fine."

Trevathan started all 16 games for the Broncos last season, leading the team with 129 total tackles. He also had two sacks, three interceptions, three forced fumbles and 10 passes defended.

The Broncos were blown out in last year's Super Bowl loss to the Seattle Seahawks and made several moves in the offseason to try to improve their defense. Losing Trevathan sets them back a bit. Denver opens the season Sept. 7 at home against Andrew Luck and the Indianapolis Colts.
