Darren McFadden might lose his spot as the Dallas Cowboys' starting running back thanks to a slippery iPhone. McFadden—fourth in the league for rushing last season—nearly dropped his brand new iPhone at his home over Memorial Day weekend. In an effort to catch it, he cracked his right elbow, a team coach tells the Dallas Morning News. McFadden underwent surgery on Tuesday and is expected to be out for at least two months. Rookie Ezekiel Elliott will take his place in training camp and perhaps even his starting position when the season kicks off Sept. 11. (More NFL stories.)
