Tom Loeffler of K2 Promotions, who handle IBF, IBO, WBA, WBC middleweight champion Gennady Golovkin (37-0, 33 KOs), indicates that his boxer will not return until at least September, hopefully against the winner of Saturday's fight between Saul "Canelo" Alvarez and Julio Cesar Chavez Jr.

Canelo vs. Chavez Jr. takes place at the T-Mobile Arena on May 6th, on HBO Pay-Per-View, at a catch-weight of 164.5-pounds.

Golovkin went through a tough contest last month at New York's Madison Square Garden, when he was taken the full twelve round distance for the first time in his career, by Daniel Jacobs.

He was initially going to fight in June or July on Kazakhstan, possibly against WBO middleweight champion Billy Joe Saunders, but he wasn't ready to return to training camp so quickly and his body was still very sore from the Jacobs bouts.

"Gennady is not going fight in June," Loeffler told ABC News. "It was a quick turnaround after the Jacobs fight and we would have liked to have done a fight with Billy Joe Saunders but it was just too quick of a turnaround. So we'll see now when Gennady is ready to fight what the biggest opportunities are."

"Gennady would have had to be in training two weeks ago already but he went 12 hard rounds with Jacobs. There was also a question on the date. Saunders' promoter] Frank [Warren] wanted to move the date up a week. He wanted to go earlier in June. Bottom line is Gennady won't fight in June. They still are anxious to have him [in Kazakhstan]. They want him to be there and Gennady wanted to fight over there but it would have been too quick of a turnaround. It was 12 hard rounds (with Jacobs)."

Loeffler and Golovkin will hang back, wait for the outcome of Canelo-Chavez, and then begin negotiations to face the winner in the fall.

"We'll see what happens. If Chavez wins we'd love to have a Chavez fight also," Loeffler said. "If Canelo wins that would be the priority. I'm still in contact with Golden Boy. I speak to (Golden Boy president) Eric Gomez probably like twice a week. We'll see what happens on May 6 and see if we can make a deal."
