On March 22, 2008, Marshall slipped on an empty McDonald's bag while wrestling with family members, and subsequently, fell through a television set at his home in Orlando, Florida – cutting his right forearm. According to Broncos head athletic trainer Steve Antonopulos, Marshall "sustained right forearm lacerations to one artery, one vein, one nerve, two tendons and three muscles." He was treated at a local hospital and later released after needing a cast and several stitches. In early April, Marshall had the cast removed from his surgically repaired right forearm and was in a sling until May. He was cleared in late-June to practice with the Broncos. He later revealed that his right hand was numb during the entire 2008 season.
