If Jose Ramirez and Josh Taylor successfully make mandated defenses of their titles over the next four weeks, their promoter hopes to match them by the end of 2020.

Bob Arum wants Ramirez-Taylor to be one of the higher-profile fights ESPN televises live on the network toward the end of this year. Arranging that 140-pound championship unification fight will require Ramirez to defeat Viktor Postol on Saturday night in Las Vegas and Taylor to get past Apinun Khongsong on September 26 in London.

“We’re moving a lot of the big fights to regular ESPN,” Arum told BoxingScene.com. “I expect we’ll have three or four big fights on ESPN this year, including Lomachenko-Lopez, possibly a Crawford fight, possibly Berchelt-Valdez and Ramirez-Taylor.”

ESPN will have some programming holes to fill on Saturday nights in the fall because numerous college football conferences have at least postponed seasons.

Vasiliy Lomachenko and Teofimo Lopez are expected to fight for Lomachenko’s WBA and WBO lightweight titles and Lopez’s IBF belt October 17 at MGM Grand Conference Center in Las Vegas. Miguel Berchelt and Oscar Valdez are tentatively scheduled to meet for Berchelt’s WBC super featherweight title November 7, though Arum stated that date could change.

Crawford will defend his WBO welterweight title November 14 against an opponent to be determined, possibly Kell Brook. If Ramirez and Taylor win their upcoming bouts, they’d take brief breaks and perhaps fight sometime in December.

Arum, who is Ramirez’s promoter and Taylor’s co-promoter, is open to staging Ramirez-Taylor in the United States or the United Kingdom. Ramirez, of Avenal, California, told BoxingScene.com a few months ago he’d have no problem boxing Scotland’s Taylor in the UK, particularly if fans are allowed to attend boxing events there before at least partial crowds can assemble at cards in the U.S.

“I don’t know much about the Thai guy, but he seems like he has a hell of a background, with all these knockouts and everything,” Arum said of Khongsong. “So, we’ll see. But if Taylor goes through and Ramirez goes through, I may be able to have them fight each other before the end of the year. We’d like to do that fight with fans, but we don’t know if that’ll be possible.”

The 28-year-old Ramirez (25-0, 17 KOs) is listed as a 7-1 favorite to defeat Ukraine’s Postol (31-2, 12 KOs). Arum considers the 36-year-old mandatory challenger for Ramirez’s WBC super lightweight title a greater threat than that, though.

“It’s a very competitive fight,” Arum said. “Postol has always been one of the guys on top at 140. He’s a tough out, so I expect a really, really good fight. Jose is coming on. He keeps getting better and better as the years go on, but it’s a very tough fight.”

Ramirez-Postol will headline an ESPN+ stream from MGM Grand Conference Center. Coverage of that eight-bout card is scheduled start Saturday at 7:30 p.m. ET/4:30 p.m. PT.

The bout between Taylor (16-0, 12 KOs) and Thailand’s Khongsong (16-0, 13 KOs), the mandatory challenger for Taylor’s IBF junior welterweight title, also will be streamed by ESPN+ four weeks from Saturday from BT Sport’s Studio.
