Broncos cornerback Tracy Porter missed his second straight game Sunday night because of symptoms he continues to experience following a seizure he had in August.
Porter was held out of practice most of the week and visited a doctor in hopes of being cleared to play against his former team, the New Orleans Saints.
He'll be replaced by Chris Harris in the base defense with Tony Carter playing the nickel.
For the Saints, tight end Jimmy Graham was active after missing last week's game at Tampa Bay with a right ankle injury.
One of his backups, Daniel Graham, was deactivated along with two defensive starters: strongside linebacker Scott Shanle and run-stuffer Brodrick Bunkley. Shanle was ill during the week but practiced.
