GREEN BAY, Wis. (AP) -- The Green Bay Packers have released veteran safety Charlie Peprah a day before their first training camp practice, apparently over concern about a lingering knee injury.

The Packers announced the move Wednesday afternoon. Asked about Peprah's status earlier in the day, Packers coach Mike McCarthy said he was "waiting for more information" from Peprah's physical exam.

Packers players reported to camp Wednesday morning for physicals and meetings. The first practice is Thursday morning.

The move leaves the Packers with even more questions at safety, where the team is looking for a replacement for Pro Bowl safety Nick Collins. The Packers released Collins in the offseason, concerned about his ability to safely return from a significant neck injury he sustained last season.
