GREEN BAY, Wis. -- Green Bay Packers inside linebacker Desmond Bishop failed his pre-training camp physical after straining his calf this past weekend while working out.
This is an injury Bishop has suffered before. The 28-year-old starter hurt both of his calves last season and missed Weeks 13 through 15 with the injuries.
There is currently no time frame for Bishop to begin participating in training camp.
"We've had some (injury) history with Desmond; it was his calf last year, missed a couple games," coach Mike McCarthy said after the team's first practice Thursday morning. "It's good that we be cautious before he gets back out there. He actually (injured) both of them last year."
McCarthy would not specify which calf Bishop re-injured.
Despite missing three games last season, Bishop led the Packers in tackles with 115 total and 90 solo takedowns. Bishop was in the top three in the NFL in tackles prior to his injury and still ended up finishing 13th overall in the league.
