The Broncos might have to play without two of their starters on the offensive line, including star rookie left tackle Ryan Clady, Sunday against Buffalo in a game in which Denver could clinch the AFC West title.
Clady and right guard Chris Kuper missed practice Thursday for the second straight day. Clady has an ankle injury and Kuper has an injured hand. Both players were hurt late in Denver's 30-10 defeat at Carolina. Clady and Kuper likely won't play against the Bills if they don't practice Friday.
If Clady is out, rookie Tyler Polumbus would likely start and if Kuper can't go, rookie Kory Lichtensteiger would likely play. He allowed a sack on the first play he spelled Kuper on Sunday. The loss of Clady would be huge for Denver. The first-round pick has allowed just half a sack all season.
Receiver Brandon Stokley also missed practice for the second straight day with a foot injury. Cornerback Champ Bailey continued to be limited by a groin injury. He will test it later this week. Bailey has missed seven straight games.
