Denver Broncos leading tackler Danny Trevathan is out six to eight weeks after fracturing his left knee during a particularly intense padded practice Tuesday.

The Broncos said their weakside linebacker has what's called a medial tibial impaction fracture but, fortunately, no torn ligaments.

Trevathan, who didn't put any weight on his left leg after being carted off the field during team drills, is expected to return to the Broncos right around their bye week in late September, meaning he'd only miss three regular season games, at most.

He was hurt on an 11-on-11 run play in which center Will Montgomery rolled over him.
