CINCINNATI (AP) _ Running back Chris Perry, Cincinnati's first-round draft pick, went on injured reserve Wednesday after a disappointing rookie season.

Rookie receiver Matt Cherry was signed off Jacksonville's practice squad to a three-year deal, taking Perry's roster spot.

Perry was the 26th overall pick in last April's draft after playing for Michigan but played in only two games because of injuries, carrying twice for 1 yard.

He strained a hamstring in the final preseason game, then strained abdominal muscles during practice on Oct. 20 and didn't play again. A specialist examined Perry last week and found he had a hernia.

He will have surgery on Jan. 6 and will need two or three months to heal.
