Sugar Ray Leonard no longer will serve as an HBO boxing commentator because the cable television network is miffed about not having a chance to be involved in Leonard's next fight, according to Ross Greenburg, HBO vice president and executive producer/sports.

Greenburg blamed the split, after 12 years, on Mike Trainer, Leonard's attorney, who did not offer HBO bidding rights on Leonard's proposed fight with Terry Norris, the World Boxing Council's junior middleweight champion.

Trainer said in Las Vegas that Leonard's broadcasting deal with HBO had expired more than a year ago and that "Ray indicated to me he didn't want to continue it, because it interfered with some things he wanted to do. To infer that there is any linkage between Ray's work with HBO and the rights to his fights is wrong. There is no such agreement and there never has been. I will always go to the person who will benefit Ray the most."

Trainer said Leonard, who has won world titles in five weight divisions, probably would fight for Showtime around January. Leonard had appeared as a fighter 11 times on HBO since 1978 and had been part of its announcing team for 10 years. . . .
