Doctors rushed to operate, and one said the damage looked like something caused by a hand grenade. Edwards tore his posterior and anterior cruciate ligaments and medial collateral ligament, partially tore his lateral collateral ligament and stretched his peroneal nerve. Most seriously, he severed an artery that supplies blood to the lower leg."After the surgery, they told me how close I was to losing my leg," Edwards said.Doctors also told Edwards his career was probably over, and he might need a cane to walk.Following a second operation, Edwards began rehabilitation. For weeks he couldn't pick up his foot or turn his ankle because of the nerve damage, and it was eight months before feeling returned in his foot. But by summer, he was walking and biking, which put him a year ahead of schedule in his recovery.
