Richard Schaefer co-promoting Dec. 10 SHO card

Richard Schaefer is back. The former Golden Boy co-boss, credited by most with being the true promoter and business mind behind the company’s biggest years, will promote his first fight in two and a half years on December 10, as he’s a co-promoter for Showtime’s world title doubleheader that night.

Schaefer and his Ringstar company will be working with Tom Brown’s TGB Promotions on the show, which will feature Jesus Cuellar vs Abner Mares in a featherweight title bout, and Jermall Charlo vs Julian Williams in a junior middleweight title tilt.

The last time Schaefer was part of a boxing card was the first fight between Floyd Mayweather and Marcos Maidana, which took place on May 3, 2014. He parted ways with Golden Boy Promotions — stepped down, was fired, whatever -- after that, and there was a lot of controversy about how many of Golden Boy’s fighters were in fact not under contract to the company, but were contracted to Al Haymon.

Schaefer’s Golden Boy departure led to a mass exodus of Haymon’s fighters, and to the eventual creation of Premier Boxing Champions, which has been at best a mixed bag in its two years in existence.
