GREEN BAY, WI (WHBL) - The Green Bay Packers will open their training camp today with seven players on the physically-unable-to-perform list. The biggest surprise is that defensive end Mike Neal failed his physical Thursday. The fourth-year defensive player was a full participant in the Packers’ off-season workouts, and he scrimmaged at outside linebacker for the first time. Also on the “PUP” list for failing physicals are running back DuJuan Harris, offensive tackle Derek Sherrod, offensive lineman J-C Tretter, defensive end Jerel Worthy, and safeties Sean Richardson and Chaz Powell. Inside linebacker Jamari Lattimore was put on the non-football illness list. Last year, the 26-year-old Neal was suspended for the first four games for taking the drug Adderall – but he came back strong to have best season as a pro, with four-and-a-half sacks and 19 quarterback pressures. Harris, who came on strong at the end of last year, was hoping to be ready for camp after having a cyst operation in one of his lungs during the off-season. At training camp, players can be removed from the “PUP” list at any time. Once the regular season begins, those on the list must stay sidelined for at least six weeks before they can start practicing with their teams. On Thursday, coach Mike McCarthy said his biggest goal is to avoid the injuries that plagued last year’s camp. Over two dozen players missed games and practices last year – and many of those missed at least a third of training camp.
