When Pro Bowl running back Robert Edwards was injured in a beach football game in 1999, he "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." Against the expectations of almost everyone but himself, Edwards made it back to the NFL last week, scoring two touchdowns for the Miami Dolphins.
