IRVING, Texas -- Dallas running back Darren McFadden fractured his right elbow in an accident at home and will likely be sidelined at the start of training camp.
Cowboys coach Jason Garrett said the accident happened during Memorial Day weekend, and McFadden returned for voluntary workouts last week. Garrett said the fracture was discovered during a physical before the mandatory minicamp that started Tuesday.
McFadden, who had surgery Tuesday, was fourth in the NFL in rushing last season with 1,089 yards. Garrett said McFadden would be out "at least a couple of months."
Dallas drafted former Ohio State star Ezekiel Elliott with the fourth overall pick in the draft and also signed free agent Alfred Morris, who made the Pro Bowl twice in Washington.
It's unclear if McFadden will be ready for the Cowboys' Week 4 game against the 49ers in Dallas on Oct. 2.
The 28-year-old eight-year NFL veteran rushed for 25 touchdowns and averaged 4.1 yards per carry over seven years with the Raiders after he was selected fourth overall by Oakland in the 2008 NFL Draft.
