The decision stems from Beckham's actions on Sunday against the Panthers.
The NFL announced Monday it would suspend Beckham for one game for his actions during the Giants’ loss to the Carolina Panthers on Sunday, citing “multiple violations of safety-related playing rules.”
Beckham and Panthers cornerback Josh Norman were involved in several physical altercations during the game, the most flagrant of which was a helmet-to-helmet hit initiated by Beckham in the third quarter. Beckham received three personal fouls, and Norman was flagged twice for unnecessary roughness.
Beckham tweeted on Wednesday afternoon explaining why he appealed his suspension, and apologizing to his teammates, the Giants organization and fans.
The Giants (6–8) play the Minnesota Vikings (9–5) on Sunday as they fight to stay alive in the NFC East. Beckham will be barred from the team facilities until Monday.
Beckham, a two-time Pro Bowl selection, is tied for the league lead in touchdowns with 13, and has logged 1,396 yards on 91 receptions through 14 games, eclipsing his season totals for 2014.
