Daniel Jacobs' ring return could come in the co-feature of the Canelo Alvarez-Gennady Golovkin middleweight world championship fight, which will take place on Sept. 16 (HBO PPV) at T-Mobile Arena in Las Vegas, according to a source familiar with the talks taking place between Golden Boy Promotions, Alvarez's promoter and the lead promoter of the card, and Al Haymon, Jacobs' adviser. Even though Golden Boy and Haymon had a bitter falling out a few years ago – Golden Boy's $300 million lawsuit against Haymon was dismissed but is under appeal – they have been able to work out fights recently. They did a deal for Alvarez to fight Amir Khan in May 2016 and Julio Cesar Chavez Jr. on May 6, and now may do one to have Jacobs (32-2, 29 KOs) featured on the card. The fight would be Jacobs' first since March 18, when the former secondary middleweight titleholder gave GGG his toughest fight in a hard-fought decision loss for the unified title. Jacobs' opponent on the card, should a deal be finalized, has not been determined, the source said.
