A U.S. District Court Judge in New York granted Elliott a temporary restraining order request regarding his six-game suspension over domestic violence allegations.
The ruling means the 22-year-old running back, a vital cog in the Dallas machine who led the league in rushing last season, can play against the San Francisco 49ers on Sunday.
The restraining order is in effect until a preliminary injunction hearing no later than Oct. 30.
In August, Elliott was suspended for six games by NFL Commissioner Roger Goodell after a year-long investigation into domestic violence accusations made by a former girlfriend.
Elliott has played all five games for the Cowboys (2-3) this season as his case moves through the court system.
