Broncos DE Zach Kerr suffered a bruised knee in the third preseason game.
The injury is expected to sideline him a couple weeks and could keep him out Week 1. It is another blow to a defensive line which will be without Billy Winn (knee) all year and has two more linemen, Derek Wolfe (ankle sprain) and Jared Crick (back), in a race to get back before the season opener. In better news, NT Kyle Peko (foot) is off the PUP.
