Elliott was handed the suspension after a roughly year-long investigation by the National Football League into allegations of domestic violence by former girlfriend Tiffany Thompson.
"In consultation with the NFLPA and his lawyers, and after careful deliberation and review of the recent Second Circuit decisions, Mr. Elliott has chose to forego any further appeals and will serve the remaining suspension", agent Rocky Arceneaux and lawyer Frank Salzano said in a statement released to PFT.
Elliott will serve his six game-suspension and is eligible to return December 24.
The latest ruling came Thursday when the 2nd U.S. Circuit Court of Appeals rejected Elliott's motion for a preliminary injunction pending appeal within an hour of hearing 35 minutes of arguments from representatives for Elliott and the NFL.
The NFL announced Elliott's suspension, for the alleged domestic abuse of a former girlfriend, prior to the start of the season.
The NFLPA immediately appealed Goodell's suspension decision, enabling Elliott to play while the case worked its way through the legal system. Commissioner Roger Goodell's power remains intact. Considering those final two games are with the Seahawks and Eagles, this goal may be asking a lot of the second year running back. However, that suspension was extended indefinitely after another video was released depicting Rice striking his fiancée in the elevator. In fact, OH prosecutors decided against pursuing a case against Elliott previous year.More news: A 7.3-magnitude quake on the Iran-Iraq border leaves hundreds dead

'You are a black male athlete, ' Elliott claimed Thompson told him, according to the report.
The NFL players' union sued on Elliott's behalf and he had been allowed to play in the Cowboys first eight games of the season while the legal process played out in court.
