For the third time in the last 11 months, Gennady "GGG" Golovkin and Roman Gonzalez will fight on the same card. Both boxers will defend their belts on Saturday night at The Forum in Inglewood, California.

Golovkin faces Dominic Wade in a middleweight title fight, while Gonzalez puts his flyweight titles on the line against McWilliams Arroyo. Both fighters retained their belts on pay-per-view at Madison Square Garden on Oct. 17, and they did the same five months prior on HBO at The Forum.

The two boxers have dominated their respective weight classes, but Golovkin is always the main event. With 21 consecutive knockouts, he’s seen a significant rise in popularity over the last few years, and could soon earn a fight against Canelo Alvarez, the hard-hitting boxer from Guadalajara, Mexico. Alvarez is the sport’s No.1 PPV draw now that welterweights Floyd Mayweather Jr. and Manny Pacquiao have retired.

Gonzalez has grown in popularity, as well, introducing the best the 112-pound division has to offer to a new audience. He’s built up enough of an audience that he could soon find himself in a main event if he puts on another brilliant performance on Saturday.

"It's been a fantastic pairing and the fans really respond when they see the No. 1 and No. 2 pound-for-pound fighters on the same show," K2 Promotions managing director Tom Loeffler said via ESPN.com. "We really worked hard to make it happen this time. If everything goes the right way -- and I mentioned this is a very difficult fight for him -- if everything goes the right way against McWilliams, then I think he will have earned the right to be a main event fighter on HBO.

"We've been pushing for [a main event], and Roman has gotten a great response from the HBO viewers, and if he wins on Saturday we will have more discussions."

Coverage on HBO is set to begin at 10 p.m. ET, and the actual start time of Golovkin’s fight will depend on what Gonzalez does. When the two boxers last fought on PPV, Golovkin’s fight against Willie Monroe Jr. began at 10:41 p.m. ET because Gonzalez needed less than two full rounds to finish off his opponent. If Gonzalez’s fight is lengthier, like his ninth-round TKO of Brian Viloria in October, Golovkin might not get in the ring until after 11 p.m. ET.

The non-televised undercard at the Forum includes a lightweight fight between Ryan Martin and Rosberg Montoya. Kenia Enriquez faces Amaris Quintana in an eight-round women’s flyweight fight.
