Julio Cesar Chavez Jr. could face either WBA 160-pound titleholder Gennady Golovkin or ex-175-pound champ Jean Pascal in July, Top Rank CEO Bob Arum told RingTV.com's Tim Smith on Tuesday.

Arum shared that sentiment, among others, during a press conference in New York, site of a June 7 clash between RING and WBC middleweight champion Sergio Martinez and Miguel Cotto at Madison Square Garden.

"July 12 it will be a pay per view with Julio," said Arum. "It will either be Golovkin or Jean Pascal."

Chavez (48-1-1, 32 knockouts) is coming off consecutive unanimous decisions over Bryan Vera, most recently in a 168-pound bout on March 1. 

Pascal (29-2-1, 17 KOs) was last in the ring for a unanimous decision over Lucian Bute in January, and Golovkin (29-0, 26 KOs), for last month's seventh-round stoppage of Osumanu Adama, representing his 16th straight knockout victory.

"I had dinner with Pascal last night. Very intelligent guy. It will be at 175 pounds," said Arum. "Pascal would like to do it in Las Vegas. I would love to do a fight like that in Cowboys Stadium."

ARUM ON GARY RUSSELL JR.-VASYL LOMACHENKO

WBO President Paco Valcarcel informed RingTV.com that he could have a plan in place by next week to produce a July featherweight fight between Gary Russell Jr. and Vasyl Lomachenko for the vacant title.

Since Russell and Lomachenko are represented by rival promoters Golden Boy and Top Rank, Valcarcel acknowledged that negotiations for a potential meeting between the two is likely to go to purse bid.

In October, both Arum and Golden Boy CEO Richard Schaefer told RingTV.com they saw no difficulties, even if the negotiations go to purse bid.

Arum addressed the situation again on Tuesday.

"If [Lomachenko] wants to do it against Gary Russell, does it go straight to purse bids?” said Arum. “We’d offer Gary Russell some dough, and if he turns it down, we’ll go to purse bids, or they could offer Lomachenko money and he might take it [or] it will end up in purse bid…"

Coming off a knockout of Miguel Tamayo in January, Russell (24-0, 14 KOs) was declared by Valcarcel in October to be the organization’s mandatory challenger to face then-beltholder Orlando Salido.

The ruling did not preclude Salido from making a voluntary defense against Lomachenko, 26, which he did on March 1.

Lomachenko fell by split-decision to Salido, who lost his WBO belt at the scales after failing to make the 126-pound weigh-in limit.
