JACKSONVILLE, Fla. — The Jacksonville Jaguars have placed starting cornerback Alan Ball on injured reserve with a bicep injury.
The Jaguars signed fourth-year cornerback Tommie Campbell to replace Ball on the 53-man roster.
Ball started 22 games for the Jaguars over the past two seasons, including seven this year.

Without him, Dwayne Gratz will move back into the starting lineup opposite fellow second-year player Demetrius McCray against Cincinnati on Sunday.
Losing Ball for the season is the latest setback for Jacksonville’s improving defense. The Jaguars (1-7) already lost starting linebacker Paul Posluszny for the season with a torn chest muscle and defensive end Andre Branch for at least five more weeks with a groin injury.
Cornerback Will Blackmon also is out indefinitely with a broken finger.
