CINCINNATI (AP) - The Bengals placed fullback Chris Pressley and quarterback Zac Robinson on the physically unable to perform list Tuesday, part of getting down to the 75-man roster limit.
Pressley has a knee injury and Robinson a sore passing elbow that sidelined them for training camp. They could be activated after the sixth week of the season if they're medically cleared.
The Bengals also put rookie linebacker Sean Porter on injured reserve with a shoulder injury, ending his season.
Second-year guard Otis Hudson and rookie offensive tackle Jason Weaver were waived. Injured linebacker Brandon Joiner was placed on waivers. If he clears waivers, he goes on the Bengals' injured reserve list on Wednesday.
The Bengals host the Indianapolis Colts in their final preseason game Thursday night.
