ARLINGTON — A special teams blunder happened at the end of the first half of Dallas’ 28-17 loss to Arizona. Aiming to cut the Cowboys’ deficit to one point, Dan Bailey watched Arizona’s Justin Bethel block a 35-yard field goal attempt and preserve the Cardinals’ 14-10 lead. The ball bounced into the hands of the Arizona’s speedy cornerback Patrick Peterson. Peterson took off and ran 60 yards before being tackled at the Cowboys’ 19-yard line by tight end Jason Witten. Asked what happened, Bailey said, “I really don’t know… The operation felt good. It’s one of those issues we have to look at on tape and kind of see what went wrong.” It was Bailey’s second blocked field goal and his first since December 2011, when Jason Pierre-Paul deflected a 47-yard attempt at the end of a 37-34 loss to New York Giants. “Looks like they bested us,” Cowboys special teams coordinator Rich Bisaccia said of Arizona. “Look at the tape, see what happened, fix it.”
