Randy Moss is almost sure to be fined for pretending to moon fans in Green Bay during a playoff win, according to NFL rules.

The league is looking into the star receiver’s antics in Minnesota’s 31-17 win over the Packers on Sunday and will announce its ruling later this week.

When asked 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.
