It was a star-studded night at Staples as current and former world champions attended the fights, including Jarrett Hurd, Errol Spence Jr., Leo Santa Cruz, Abner Mares, Gervonta Davis and Adrien Broner.
They sat ringside to watch Mikey Garcia win a dominant twelve round unanimous decision over previously undefeated Robert Easter to unify the WBC and IBF lightweight world titles.
Shawn Porter was also in attendance. It was recently announced that Porter and fellow former 147-pound world title holder Danny Garcia will square off against one another for the vacant WBC Welterweight World Championship live on Showtime Saturday, Sept. 8 from Barclays Center in Brooklyn, N.Y.
He's very confident of handing Garcia the second defeat of his pro career.
"I'm just a different type of athlete," Porter told Showtime's Brian Custer. "When you talk about having the tools to become a two-time world champion; I have the tools, the athleticism, the tenacity the ring generalship. You will see all of that on Sept. 8.
"We always say that the business has to make sense [to make fights], And it sounds to me like the business has played its part. I win the WBC Championship and you'll get Shawn Porter vs. Errol Spence."
