Fred Jackson will miss the rest of the year with a broken bone in his lower right leg, an injury that could derail Buffalo's season. The team placed Jackson on IR Wednesday, hours after coach Chan Gailey said the running back wouldn't play Sunday against the Jets. "That's disappointing news for our team and certainly for Fred," Gailey said in a statement released by the team. "He was having a great year. The process for Fred to return to the field would most likely take him through the end of the season, so we have made the difficult decision to place him on injured reserve."
