let Favre interfere with Walker's squabble with management. "There's an unwritten rule that players stick together," Walker said. Walker said he would not show up for training camp or come back at all for the final season of his contract regardless of whether Favre decided to retire or return. He said he'll repay the Packers the prorated portion of his signing bonus to leave Green Bay. "Why should I risk another year of getting beat up playing for a team that I don't want to play for? That's stupid", Walker said. Walker said he'll be ready for the 2006 season wherever he lands. "If I'm going to go out and take hits, it's going to be for a team that I love playing for", Walker said. "I'm not going to grandstand. I just want the Packers to give me peace of mind."

Following the Broncos' season finale against the San Francisco 49ers, Walker was in a vehicle that was shot at in downtown Denver, killing teammate Darrent Williams.

Walker said in an interview with Andrea Kremer of HBO's Real Sports that the attacks likely stemmed from a confrontation with bar patrons involving rookie wideout Brandon Marshall and his cousin. On February 29, 2008, the Broncos released Walker after being unable to trade him.
