Packers cornerback Tramon Williams left Thursday night’s game against the Saints after hurting his shoulder, but the injury does not appear to be serious.

Coach Mike McCarthy seemed optimistic as he said today that Williams has a shoulder bruise and will be re-evaluated next week.

McCarthy also said safety Nick Collins suffered a bruised wrist and will be ready to go next week.

In non-injury news, McCarthy reiterated that Randall Cobb made the wrong decision when returning a kickoff eight yards deep in the end zone on his NFL-record 108-yard kickoff return. But he said he was glad Cobb was decisive, and obviously he was happy with the result.

And McCarthy said he thinks Aaron Rodgers is playing with a chip on his shoulder right now. If a chip on his shoulder is what it takes for Rodgers to play like he played on Thursday, Packers fans should hope he keeps that chip on his shoulder all season.
