A day later, Raiders head coach Jack Del Rio was still disputing a pivotal fourth-down ruling in his team’s 20-17 loss to the Cowboys on Sunday night. With 5:06 left in a tied game, Dallas quarterback Dak Prescott ran a sneak on 4th-and-1 from his 39. A long official measurement ensued that included referee Gene Steratore trying to fit a piece of paper between the ball and the first-down marker. Steratore awarded the Cowboys a first down. On Monday, Del Rio was still not convinced by the “mysterious” call. “Just stretch the chain and if (the ball is) inside, if there’s space, it goes the other way,” Del Rio said. “I saw space and in my opinion, it should have gone the other way. “I haven’t had a chance to call and get the explanation. I’m sure there’ll be some kind of explanation. But whatever it is, I’m going to disagree with it.” Steratore did give an explanation to a pool reporter after the game, saying he used the paper only to “reaffirm” his initial call.
