"Defensive tackle Andre Neblett and safety Jordan Pugh will miss the Panthers' game Sunday at New Orleans as they continue to deal with concussion issues. Coach Ron Rivera said Ogemdi Nwagbuo will start in Neblett's place along the defensive front while Jonathan Nelson, who had an interception last week against Tampa Bay, will back up Charles Godfrey and Sharrod Martin at safety. Defensive end Charles Johnson may also miss the New Orleans game due to a back issue. Rivera said he plans to start Antwan Applewhite at defensive end if Johnson does not make the trip. A decision on Johnson's availability is expected this morning. The Panthers activated former N.C. State defensive tackle DeMario Pressley off the practice squad. The Panthers have also added former J.C. Smith player Kevin Sullivan to the practice squad. Also, wide receiver Legedu Naanee had surgery to repair the broken bone in his foot. The Panthers placed Naanee on the injured reserve list Friday in order to activate Pressley. Sticking around? Second-string quarterback Derek Anderson knows the starting job belongs long-term to Cam Newton but that doesn't mean the veteran wants to go someplace else next season. "I'd like to come back and continue (working with Newton and quarterbacks coach Mike Shula) because I think this team has a lot of potential. I want to be around to see it," said Anderson, who signed a one-year deal during training camp."
