The Cincinnati Bengals receiver has legally changed his name to Chad Javon Ocho Cinco in Broward County, Fla., a switch that became official this week, according to several media reports. Johnson, who lives in Miami, didn't return a message left on his cell phone Friday night.

"It's something I don't think anyone has ever done before," he told the team's Web site. "Have I ever had a reason for why I do what I do? I'm having fun."

Two years ago, Johnson gave himself the moniker - a reference in Spanish to his No. 85 - and put it on the back of his uniform before a game. Quarterback Carson Palmer ripped it off before the kickoff. After the season, coach Marvin Lewis - who dislikes Johnson's attention-getting stunts - referred to the receiver as "Ocho Psycho."

Bengals spokesman Jack Brennan said the Bengals had no comment on the matter.

Johnson has been a concern for the Bengals this season. He unsuccessfully lobbied for a trade in the offseason, threatening to sit out if he didn't get his way. When the Bengals refused, he relented and showed up for minicamp, but complained that his right ankle was bothering him.

He had bone spurs removed from the ankle and was limited at the start of training camp. In the second preseason game, he landed awkwardly and temporarily dislocated his left shoulder. Johnson is wearing a harness and expects to play in the season opener against Baltimore.
