A few notes from around the boxing world:

• Mike Trainer, the longtime attorney and adviser to Sugar Ray Leonard, died Dec. 2 at his home in Bethesda, Maryland. He was 74. Trainer helped guide Leonard, beginning with his pro debut, by steering him through the complicated boxing business without signing with a promoter, which was unheard of at the time. But Trainer did a superb job on Leonard's behalf, helping him get wide network television exposure and large purses without a promoter, in essence doing what Floyd Mayweather did long before Mayweather came along, which was to have Leonard keep the majority of the money he generated. It rubbed a lot of people in the business the wrong way but Trainer's method set Leonard up for life.

• Former bantamweight titleholder Randy Caballero (22-0, 13 KOs), 25, of Coachella, California, is moving up to junior featherweight, Golden Boy Promotions vice president Eric Gomez told ESPN.com. He will fight in that weight class against an opponent to be determined on Feb.5 (Estrella TV) at the Fantasy Springs Resort Casino in Indio, California, where he has fought most of his fights. Caballero was supposed to defend his bantamweight title against England's Lee Haskins on Nov. 21 on the Miguel Cotto-Canelo Alvarez undercard, but Caballero was stripped of the title for failing to make weight. He weighed 123½ pounds, a stunning 5½ over the 118-pound division limit.

• Golden Boy Promotions CEO and Top Rank's Bob Arum are in discussions in an attempt to make a fight between welterweight contenders Sadam Ali and Jessie Vargas for early 2016 on HBO. Ali, who is with De La Hoya, is the mandatory challenger for world titleholder Timothy Bradley Jr. But with Bradley in the hunt for a bigger fight, perhaps a third meeting with Manny Pacquiao on April 9, he is unlikely to face Ali. So if the title becomes vacant, which is a good possibility, Ali (22-0, 13 KOs) would meet Arum-promoted Vargas (26-1, 9 KOs), for the vacant belt. There had been a deal in the works for them to fight Dec. 19 for the interim title but it fell through.
