Porter became ill before a Week 6 victory over the San Diego Chargers. He has yet to be cleared to play since being diagnosed with onset symptoms of a seizure (after suffering an epileptic seizure in August), but the fifth-year veteran returned to practice three weeks ago and has a "decent chance" to see limited action against the Cleveland Browns, The Denver Post reported.
"As far as Tracy goes, they're all competitors," Fox told the newspaper. "They want to play. He got injured or had an illness, some guys stepped in and did well. He just needs to focus on getting better every day. I saw good improvement last week. He went a month without playing. So he's working his way back."
Porter has likely lost hold of his starting job because of the play of his fill-in, Chris Harris, and nickelback Tony Carter. Champ Bailey remains the team's best cover corner, but Harris especially has made a string of big plays in Porter's absence. Denver welcomes more helping hands, but when Porter last played, the Broncos were in search of themselves on defense. Since that time, they've grown into a beast.
