EAST RUTHERFORD -- Giants wide receiver Odell Beckham is on thin ice with the NFL even before his rematch with Josh Norman.

Fox Sports' Jay Glazer reported on Sunday morning that Beckham was fined $36,000 for a blindside block on Saints safety Kenny Vaccaro in the Giants' 16-13 win last Sunday. Beckham was not penalized for the hit during the game.

The replay of the hit that aired on Fox's pregame show spotlighted Beckham hitting Vaccaro in the back away from the play. Vaccaro had given Beckham a hard shove as the receiver went out on his route, and Beckham circled back to deliver the shot from behind.

Glazer said that Beckham's fine was so hefty because he is a "repeat offender." Beckham, of course, was suspended for one game last season for a vicious blindside hit to Norman's helmet when the cornerback was a member of the Panthers. Beckham and Norman, who now plays for the Redskins, will meet on Sunday at MetLife Stadium (1 p.m., FOX).

Beckham vowed earlier this week to keep his cool in his rematch with Norman. If Beckham has another blatant unsportsmanlike penalty he could be in jeopardy of another suspension, according to Glazer.

Officials were spotted have extensive pregame conversations with Norman and Giants coach Ben McAdoo before Sunday's game. The officials are well aware of the history between Beckham and Norman, and they will be keeping a close eye on any unsportsmanlike behavior.
