Dallas Cowboys running back Ezekiel Elliott must immediately begin serving his six-game suspension after a judge from the Southern District Court in New York denied him a preliminary injunction in his case against the NFL.

On Monday, Judge Katherine Pok Failla disagreed with her colleague Judge Paul Crotty’s decision to give the Cowboys running back a temporary restraining order.

The case was initially assigned to Failla, however, she was on vacation and unable to hear the case. Tasked with filling in for Failla, Crotty gave Elliott a temporary restraining order on October 17 and left the ruling for his colleague to make upon her return.
