Broncos' Porter still dealing with illness

Denver Broncos cornerback Tracy Porter was listed as doubful for Sunday's game at the Cincinnati Bengals.

Porter had symptoms last month that matched those that preceded a seizure he suffered in August, and hasn't yet been cleared to play in a game.

"We're still regulating the medication. Not that it was a setback, but there was a little bit of an issue, and we'll evaluate that moving forward," said Broncos head coach John Fox. "His safety is what's the utmost concern right now."

Fox said he wasn't sure if Porter would travel with the team.

If he doesn't play, Chris Harris and Tony Carter would likely help fill his void again.
