Health is key issue for Desmond Bishop

The quick series of events that led linebacker Desmond Bishop to schedule a Tuesday visit with the Minnesota Vikings suggests significant interest from both sides. The Vikings would get an experienced hand at a position of uncertainty, while Bishop would have a clear path to a starting job after missing an entire year because of injury -- not always a sure thing in the Not For Long league.

The real question is Bishop's long-term health prognosis. He has been telling reporters that the torn hamstring that cost him the 2012 season is fully healed, and that his absence from organized team activities (OTAs) and minicamp was the result of a strained hamstring. It's pretty clear that the Packers have had reservations about his health for a while, prompting them to re-sign veteran Brad Jones and also keep A.J. Hawk's salary in line with established starters.

It's worth noting that coach Leslie Frazier has been careful not to commit publicly to Erin Henderson as his middle linebacker, even though Henderson's internal competition is nominal at best. Signing Bishop to play middle linebacker would allow Henderson to return to the outside along with veteran Chad Greenway. First, however, the Vikings need to make a more educated projection of Bishop's health. That starts Tuesday.
