MILWAUKEE -- The NFL is flagging Sen. Russ Feingold's latest ad for using an unauthorized clip of Randy Moss pretending to moon the Green Bay crowd in 2004.
NFL spokesman Greg Aiello said Tuesday the league did not license the footage and has contacted the Democratic senator's campaign about removing it.
The ad shows a number of clips of football players dancing in the end zone. Then Feingold says the celebrations are similar to how his challenger seems to be declaring himself the victor prematurely.
Polls show Republican Ron Johnson with a slight lead over Feingold.
The Feingold campaign didn't immediately return a message asking whether it would pull the ad.
The NFL clip shows Moss pretending to moon the crowd when he was with the Minnesota Vikings. The stunt drew a $10,000 fine.
