Oscar De La Hoya, the CEO of Golden Boy Promotions, has confirmed that even though Saul "Canelo" Alvarez (49-1-1, 34 KOs) is the challenger - it will be IBF, IBO, WBA, WBC middleweight champion Gennady Golovkin who will enter the ring first for their upcoming mega-bout.

Canelo will challenge Golovkin on September 16th, in the main event of an HBO Pay-Per-View, from the T-Mobile Arena in Las Vegas.

"Golovkin is the champion, but Saul is the one who is at the helm of this promotion. Yes [Golovkin will enter first], that's how it's going to be," De La Hoya told ESPN Deportes. "Golovkin will come in first, because obviously the fighter who is the star of [of the fight] is the one who enters the ring last. That is why throughout the promotion, the one that comes in first is Golovkin, because the main star in this event is Canelo. He is the star of this sport right now."

The promotion was long and took months to finally put together.

"That's the way it was, the deal we were in. The negotiations were very difficult, long, but at last we managed to agree to this fight that everyone wanted and had been waiting for," De La Hoya said.

Canelo was last seen in action during Cinco De Mayo weekend in Las Vegas, when - as the WBO junior middleweight champion - he moved up by over ten-pounds to a catch-weight of 164.5-pounds to win a lopsided twelve round decision over Mexican rival Julio Cesar Chavez Jr.

For his part, Golovkin stepped in the ring in March, when he won a twelve round unanimous decision over Daniel Jacobs at New York's Madison Square Garden. It was the first time in Golovkin's career where he went the full twelve round distance. And Jacobs was able to snap Golovkin's streak of 23 knockouts.
