NFL Notes: Cowboys release WR Lucky Whitehead after arrest

The Dallas Cowboys have released receiver and kick returner Lucky Whitehead after the third-year player was linked to a shoplifting arrest in his home state of Virginia, with his agent saying he believes it was a case of mistaken identity. Whitehead said he "didn't know about that" as he was escorted off the field by a member of the Cowboys' public relations staff after the first morning walkthrough practice of training camp Monday in Oxnard, California. Prince William County Police Sgt. Jonathan Perok said 25-year-old Rodney Darnell Whitehead Jr. was arrested around 1:30 a.m. June 22 for taking about $40 worth of food and drink from a convenience store.
