The Jacksonville Jaguars have placed starting cornerback Alan Ball on injured reserve with a bicep injury.

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 last five more weeks with a groin injury.
Cornerback Will Blackmon also is out indefinitely with a broken finger.
