Ezekiel Elliott and the NFL Players Association are playing out the options left to them, promising or not, in an attempt to get the Cowboys running back on the field.

The union officially gave notice Tuesday that it is appealing to the 2nd U.S. Circuit Court of Appeals. Federal Judge Katherine Polk Failla, of the Southern District of New York, on Monday night denied Elliott a preliminary injunction that would have continued to block the NFL from enforcing its six-game suspension of Elliott.

Elliott's team will ask the federal appeals court to review the decision on an expedited basis. It had also asked Failla for a limited injunction that would allow Elliott to play while the 2nd Circuit weighs the request. The judge denied the request almost immediately, noting it would essentially serve as a reversal of her decision the night before.
