Golden Boy chief executive Richard Schaefer is awfully busy juggling a bunch of fights that are coming up, including the big one, Floyd Mayweather-Canelo Alvarez on Sept. 14. But there are a lot of other fights to get done also, undercards to load up and Showtime dates to fill.

Schaefer, who has been in Mexico on business, told ESPN.com that he and Al Haymon, Mayweather’s adviser and manager to many of Golden Boy’s fighters, plan to sit down in the coming days when they are both back in Los Angeles to go over a host of issues. Among them: ironing out the Mayweather-Alvarez Showtime PPV undercard and trying to finalize a Sept. 7 fight between Danny Garcia and Lucas Matthysse (both Haymon clients) for junior welterweight supremacy.

Here’s an update from Schaefer on a variety of things he’s working on:

• Schaefer said his main focus is getting Garcia-Matthysse done.

“That’s what I’m working on this week,” he said. “I’d like to have the August and September schedules all done by the end of the week. I need to sit down with Al though and figure everything out.”

Schaefer said while some have been skeptical that Haymon would go through with Garcia-Matthysse, he is not.

“Al realizes that having all these fighters means they will sometimes have to fight each other,” Schaefer said. “Danny Garcia has never turned down anybody. And Matthysse? This is the fight he’s been waiting for. The fighters want it and the adviser is on board. I just have to finalize the money and the site. But I think we will get this done.”

• Former welterweight titlist Victor Ortiz, healed from his broken jaw after a knockout loss to Josesito Lopez last June, is expected back in action either late this summer or in the fall. Schaefer said one fight he is considering trying to make is Ortiz against Shane Mosley, who is coming off a desperately needed win against Pablo Cesar Cano on May 18 after exiting retirement.

This is not a fight I am a fan of, especially considering all of the top guys Schaefer could match Ortiz with. For example, I love the idea of an Ortiz fight against Robert Guerrero, a fight Guerrero also wants. Ortiz (two losses in a row) and Guerrero are both coming off defeats, but it would definitely be a fan-friendly fight with the winner putting himself back on track.

With regard to an Ortiz-Mosley fight, Schaefer said, “I would like to see it. Both guys have a lot to prove if they want to fight for a title again. I ask people, ‘Who do you think wins?’ And the response is split. That makes it an interesting fight to me.”

• Golden Boy recently won the purse bid for the mandatory fight between junior featherweight titlist Victor Terrazas and Leo Santa Cruz and needs to schedule the bout. Schaefer said it could wind up on the Mayweather-Alvarez pay-per-view. But so, too, could featherweight titlist Abner Mares’ next fight.

“It could be Mares against [former titlist] Jhonny Gonzalez,” Schaefer said. “Gonzalez would love to fight for the title and you know how Abner is. He’s never worried about fighting anybody.”

There is also the possibility, Schaefer said, of Mares and Santa Cruz not appearing on the PPV undercard and instead having their next fights in Mexico, possibly on the same card. It is also possible that one will be on the PPV and one will fight in Mexico.

• With Marcos Maidana defeating Josesito Lopez last Saturday in a barnburner, Schaefer said Maidana is in line for two potential fights. One would be a match with Andre Berto should Berto defeat Jesus Soto Karass on July 27 in San Antonio in the main event of a Showtime tripleheader. The other could be a shot at the winner of the June 22 fight between welterweight titlist Paulie Malignaggi and Adrien Broner. Maidana could shadowbox and I’ll be watching, so either fight sounds good to me, but I love Maidana-Berto. Can you say fight of the year?

“Maidana-Berto, Maidana with the Paulie-Broner winner, both are great fights,” Schaefer said. “We have so many guys at 140 and 147 you can mix and match any of these guys. It’s insane.”

• Schaefer said in addition to the Sept. 7 and Sept. 14 cards, he will also have a major card on either Aug. 24 or Aug. 31.
