NFL Network's Adam Schefter reports Javon Walker (knee) appears unlikely to play against the Colts on Sunday.
Walker, who has been dealing with inflammation in his surgically repaired, knee, did not practice at all during the week. Schefter was formerly a beat writer for the Broncos, so his sources are good in Denver. Domenik Hixon could pick up a start Sunday, though he'd be a weak fantasy play. Walker's absence especially affects Jay Cutler, who now is a poor start.
