Broncos' Porter unavailable for Saturday

Denver Broncos cornerback Tracy Porter will not suit up when the team hosts the Baltimore Ravens on Saturday in the AFC Divisional round of the playoffs.

Porter, who was limited to just six games in 2012 due to the after-effects of a seizure he suffered in August, has since been hampered by a concussion that he sustained in the Broncos' Week 16 victory over the Cleveland Browns. He was unable to practice all week.

He played in Denver's first five games before sitting out nine straight contests while recovering from post-seizure symptoms.
