Quarterback Matt Schaub is feeling better and is expected to play Sunday against the San Diego Chargers.  Head coach Gary Kubiak says Schaub is still bothered by injuries in the hip, thigh, lower back and ankles, so it’s possible Schaub won’t be able to start.  He’ll have to show a lot of improvement by Sunday for him to start, and Kubiak says his biggest concern is protecting Schaub and being sure that Schaub can protect himself on the field.
