It looks like Miami Lakes (Fla.) Mayor Michael Pizzi’s next fight is with the federal government – not Hialeah Mayor Carlos Hernandez.

The two South Florida mayors were set to square off next month in an MMA bout for charity, but Pizzi was arrested Tuesday alongside another South Florida mayor on bribery charges, according to the Miami Herald.

Pizzi and the other mayor, Manuel “Manny” Maroño, of Sweetwater, were the subject of an FBI sting investigation, according to the report.

Pizzi was preparing for the fight just before his arrest, which Hernandez called “a very unfortunate event for not only Miami Lakes and Sweetwater, but all of South Florida.”

Dubbed “MMA Mayhem at Milander: Mayor vs. Mayor,” the bout was set for Sept. 6 at Hialeah’s Milander Auditorium.

In May, the mayors talked up the fight in separate interviews with MMAjunkie.com (www.mmajunkie.com). Hernandez planned to raise money for Best Buddies, a non-profit charity for people with intellectual and developmental disabilities, while Pizzi targeted college scholarships and anti-child obesity efforts.

The pair conceived the bout after a friendly dinner and some alcohol led to talk about who was the tougher man.

Hernandez said he had trained with the Gracie family, while Pizzi called himself a “Brooklyn street-brawler.”

Pizzi, however, said the fight wasn’t just for bragging rights, but to set a good example for Florida citizens over 50.

“It gives us an excuse to get into shape, so people don’t laugh when we take off our shirts,” he said.

Hernandez told the Herald that ticket buyers would be issued full refunds.
