The NFL has lightened up on touchdown celebrations this season, but touching the goal post remains a no-no.

Vikings receiver Stefon Diggs found that out the hard way: He hugged the goal post to celebrate a touchdown on Sunday. That cost the Vikings a 15-yard penalty, and now it cost Diggs some money as well.

The NFL has fined Diggs $12,154 for the move. That’s a typical fine for an unsportsmanlike conduct penalty.
