Free agent FB Leonard Weaver (foot) concedes that a return to the NFL is "not going to happen this season." Weaver is recovered from his torn ACL and PCL, but the muscle that allows a player to flex his left foot was "completely destroyed" and the nerve damage hasn't healed sufficiently. Weaver was told by Dr. James Andrews two years ago there was a "99 percent" chance he'd never play again. He recently failed an Eagles physical because his foot "didn't work" well enough to flex. Weaver's injury is similar to the one that ended the career of Dolphins Hall of Fame center Dwight Stephenson back in 1987.
