Wayne Huizenga

Former Miami Dolphins owner and billionaire businessman H. Wayne Huizenga's son pleaded not guilty Thursday to a boating under the influence charge.

Robert Ray Huizenga, 47, is on probation for a 2003 DUI charge for an accident that seriously injured a 71-year-old pedestrian. As a condition of his probation, a judge had prohibited Huizenga from drinking alcohol. 

Thursday, Huizenga denied that he had violated his probation. 

Broward Judge Michele Towbin Singer set Huizenga's next court date for Sept. 2. 

Huizenga's attorney, David Bogenschutz, said he will likely make a request that Huizenga be released on bond before then. But in the meantime, he will stay in jail.

Huizenga was arrested and charged with drunken boating after police said he tried to dock at the wrong house on a Fort Lauderdale canal Monday night. 

The mistake, which led to Huizenga's fourth arrest on DUI charges, could send him to prison for five years, officials said. 

On Dec. 5, 2003, Huizenga hit Irwin Louis Feigenbaum with his Range Rover as Feigenbaum crossed Las Olas Boulevard. 

After that accident, Huizenga faced up to six years in prison when he pleaded no contest to a felony DUI charge and a misdemeanor count of refusing to submit to a blood/breath test. Circuit Judge Michael Kaplan imposed a 120-day jail sentence to be followed by a year of house arrest. 

Huizenga spent a year appealing the sentence and then ultimately served 83 days in jail and won a bid to end house arrest more than five months early. 

At numerous court hearings, Huizenga voiced his dedication to recovery and sobriety. On Nov. 19, 2006, he told a judge: ``I am not the reckless person that I once was.''
