Englewood, CO (Sports Network) - Denver Broncos cornerback Tracy Porter has been ruled out for Sunday's game against the Cincinnati Bengals.
The fifth-year pro out of Indiana returned to practice on Wednesday, albeit in limited fashion after not playing in last Sunday's 34-14 victory due to light-headedness and a rapid heartbeat, symptoms that preceded a seizure he suffered in August.
Porter was able to participate fully in Thursday's practice, but wasn't able to practice on Friday.
In five games this season, Porter has totaled 21 tackles and one interception returned for a touchdown.
In addition, quarterback Peyton Manning (thumb), safety Mike Adams (knee), guard Chris Kuper (forearm) and tight end Jacob Tamme (hip) are listed as probable.
