The Broncos signed CB Tracy Porter for games like Monday night's -- games against an elite quarterback who has multiple receiving threats. But they'll have to do without Porter, who has been ruled out for Sunday's game.
Porter has an illness, the Broncos announced, and he didn't make the team flight to San Diego for Monday's game. He had practiced all week.
Chris Harris will move from nickelback to starting RCB opposite Champ Bailey, and Tony Carter is expected to replace Harris as the nickelback. When the Broncos go to a six-DB package, they'll use rookie CB Omar Bolden or one of their backup safeties -- Jim Leonhard or David Bruton -- depending on the situation.
