While Schaub participated in a good portion of practice, backup Sage Rosenfels took most of the snaps in team drills.
"Actually, Matt did a lot more than I thought he would," coach Gary Kubiak said. "I would say it's a big step in the right direction. Matt definitely looked better today."
Schaub was injured when Tennessee's Albert Haynesworth delivered a helmet-to-helmet hit on him just before halftime Sunday. Schaub had left the game earlier after a hard hit on his left leg, but returned after a short stint on the sideline.
He said he is feeling better each day and is trying to keep his hip "loose" and not do too much. A key to whether he'll play this week will be if he can gain enough mobility to protect himself when he drops back to throw.
"Just being able to move around, make some plays," he said. "Because in this game you have to be able to move around and make some plays outside the pocket, within the pocket and to avoid pass rushers and blitzers. So I just want to make sure I feel comfortable that I can do that."
