That's an expensive sombrero

Cincinnati Bengals receiver Chad Ochocinco reportedly has been fined $30,000 for donning a poncho and sombrero after scoring a touchdown.

Ochocinco wore a gray poncho and black sombrero after catching a TD pass in Cincinnati’s 23-13 victory over the Detroit Lions on Sunday.

NFL rules prohibit players from bringing any extraneous object onto the field.

On his Twitter account, Ochocinco posted Tuesday: “Dear NFL League Office ... being great means having fun

 • celebrating. I’ve written a letter of apology to yall.”

This punishment comes about a month after Ochocinco was fined $20,000 and reprimanded by the NFL for pretending to bribe an official a dollar.
