Bishop, 30, is a former sixth-round pick of the Packers. He spent five years with Green Bay and helped them win a Super Bowl before he suffered a serious hamstring injury that cost him the 2012 season.
Bishop later caught on with the Vikings, but unfortunately suffered a torn ACL and was placed on season-ending injured reserve. The Cardinals signed him to a contract a few weeks ago and he managed to make through roster cuts, but was released soon after.
He has recently visited with the Jets and Chiefs since he was cut loose by the Cardinals.
