Randy Moss has been told he will be fined $10,000 for his end-zone celebration, a Vikings source told ESPN’s Chris Mortenson on Thursday.

NFL officials would not confirm or deny the report.

Moss caught a touchdown pass in the fourth quarter of the Vikings’ 31-17 win over the Packers on Sunday and headed toward the goalpost. He then turned his back to the Lambeau Field crowd, bent over and pantomimed pulling down his pants.

Moss didn’t practice with the Vikings on Wednesday because of a sprained right ankle, but he’s listed as probable for Sunday’s playoff game at Philadelphia.

Sunday night, an NFL spokesman told ESPN’s Chris Mortensen: “Randy Moss can expect to be hearing from us.”

When asked by The Associated Press whether the oft-fined Moss would be penalized again, a league spokesman recited NFL rules mandating discipline for “obscene gestures or other actions construed as being in poor taste.”

A fine for the first offense under those guidelines is $5,000. Moss has not previously been fined for such action, but paid a $25,000 penalty in 1999 for squirting an official with a water bottle.

Moss, making $5 million this season, declined comment Monday.

Last month, Denver quarterback Jake Plummer was fined $5,000 for an obscene gesture.

Moss had four receptions for 70 yards and two touchdowns in Sunday’s game.
