David Purdum of ESPN reported Shaw is now listed in the Reserve/Suspended by Commissioner list, signaling he has dropped his appeal. Shaw was suspended by the NFL on Nov. 29 for making several bets on NFL games during a trip to Las Vegas with friends.
"The continued success of the NFL depends directly on each of us doing everything necessary to safeguard the integrity of the game and the reputations of all who participate in the league," NFL commissioner Roger Goodell said in a press release. "At the core of this responsibility is the longstanding principle that betting on NFL games, or on any element of a game, puts at risk the integrity of the game, damages public confidence in the NFL, and is forbidden under all circumstances. If you work in the NFL in any capacity, you may not bet on NFL football."
The NFL investigation found Shaw bet on several games this season while on injured reserve. Included in those contests was a three-game parlay in which he bet against the Cardinals during their matchup with the Tampa Bay Buccaneers.
It's not believed that Shaw used any inside information to place his wagers. He cooperated with the league's investigation into the matter and had been appealing to reduce his suspension.
The USC product is the first player to be suspended since a Supreme Court ruling allowed individual states to legalize sports gambling.
