SAN DIEGO (AP) -- The San Diego Chargers have placed rookie linebacker Jonas Mouton on injured reserve with a shoulder injury, meaning he's out for the season.
Mouton, a second-round draft pick from Michigan, was hurt in the exhibition finale and was inactive the past two weeks.
To take his roster spot, the Chargers signed safety Paul Oliver to a one-year contract. Oliver was with the Chargers from 2007 through last season before leaving as an unrestricted free agent. He signed with the New Orleans Saints before being released following training camp.
Also Wednesday, wide receiver Malcom Floyd, who hurt his groin in Sunday's 35-20 loss at New England, was one of five players who didn't practice. Coach Norv Turner says tight end Antonio Gates (foot), defensive end Corey Liuget (ankle), safety Bob Sanders (knee) and running back Mike Tolbert (calf) were sorer than expected and might be able to practice Thursday.
