The former first-round draft pick had surgery last July and started the season on an injury list. The Bengals got a three-week roster exemption that allowed him to work out with the team. The exemption ended on Tuesday, and Cincinnati decided to leave him on the injury list, ruling out a return this season.
Rivers was the ninth overall pick in 2008. He broke his jaw on a hit by Steelers receiver Hines Ward during the seventh game of his rookie season and didn't return. He missed three games in 2009 with a calf injury. He played in 15 games last season despite a foot injury.
