RB Ezekiel Elliott of the Dallas Cowboys plans to attend his six-game suspension appeal hearing at NFL headquarters in New York on Tuesday. Stephen Jones, the Cowboys’ executive vice president and CEO, confirmed to reporters Friday that Elliott will not be at practice on Monday and Tuesday to prepare for the appeal hearing. Arbitrator Harold Henderson, who was appointed by NFL commissioner Roger Goodell to hear the appeal, has denied a request from Elliott’s representatives to make his accuser, former girlfriend Tiffany Thompson, available to testify , according to Pro Football Talk’s Mike Florio. The 22-year-old Elliott was suspended by the NFL on Aug. 11 for violating the NFL’s personal conduct policy. The ban stems from the league’s 13 month-long investigation into domestic violence accusations made against Elliott by his former girlfriend.
