Receiver Andre Johnson, tight end Owen Daniels and linebacker Xavier Adibi were all held out of practice Thursday, but quarterback Matt Schaub got all his normal reps after being limited Wednesday.
Although Schaub took a hard shot to the ribs against the Chargers, both he and coach Gary Kubiak are disinclined to dwell on the extent of the injury.
"He's fine," Kubiak said. "He took his full load today and was very upbeat. He'll be OK."
Daniels, battling a pulled hamstring, seems likely to miss his second consecutive game Sunday, but Kubiak is calling him "a game-time decision." Johnson, who has a bad ankle, was held out more for precautionary reasons.
