An NFL source says Cincinnati Bengals wide receiver Chad Ochocinco has been fined $30,000 for donning a sombrero and poncho after a touchdown reception Sunday against the Detroit Lions.

In a letter the NFL sent this week to Ochocinco, the league wrote, "During the second quarter of the Bengals qame, you were observed gesturing for, and then wearing, a decorative poncho and sombrero in the bench area. ...

"Compounding your violation is the fact that your actions were premeditated and deliberate. Prior to the game on your publicly accessible Twitter account, you posted the following: '@adam_schefter what I've planned for today will get me fined when I score but it's so worth it.'"

Ochocinco was also slapped with a $20,000 fine for a stunt with a dollar bill last month during a replay challenge in which he "fake bribed" an official.
