Walker, Bailey, Hurt

Denver Broncos wide receiver Javon Walker could miss six weeks after undergoing surgery on his right knee Friday, coach Mike Shanahan said. Walker could be back sooner, but it's too early to tell, Shanahan said Walker's surgery in Houston. "I heard the doctor estimate it at six weeks. We'll get a better feel on it next week or so," Shanahan said. Walker, who missed the Broncos' last two games because of excessive swelling and pain, tore his ACL during the 2005 season-opener with the Green Bay Packers. He had two surgeries to repair the knee that season and needed a follow-up operation around the time he joined the Broncos in a draft-day trade in 2006. The Broncos could certainly use his big-play ability. The team is 2-1 when he plays and 0-2 without him. Walker had 17 catches for 220 yards in the team's first two games before being held to just 2 catches and 10 yards against Jacksonville in week 3. The Broncos also may be without their best defensive player -- cornerback Champ Bailey -- when they host Pittsburgh Sunday night. Bailey will be a game-time decision, Shanahan said. Bailey returned to limited practice Friday after missing the rest of the week because of a strained right quadriceps.
