Chad Ochocinco was relatively quiet with the New England Patriots last season.
But the newly signed Miami Dolphins wide receiver sent a warning to NFL commissioner Roger Goodell on Twitter on Monday: Get ready, the old Ochocinco is back.
The NFL has repeatedly punished Ochocinco for his antics. In 2009, the receiver was fined $20,000 for pretending to bribe a referee and, weeks later, $30,000 for wearing a fake poncho and sombrero after scoring a touchdown.
His touchdown celebrations have often earned the most attention from the NFL. His many fines include one for $10,000 in 2003 for pulling out a sign reading, "Dear NFL, PLEASE don't fine me AGAIN!!!!!"
