Horn, 29, won the title last July with a highly controversial decision against eight-weight world champion Manny Pacquiao.
“Pac Man” was expected to agree to a November rematch but pulled out due to his Senatorial duties in the Philippines taking priority.
Top Rank founder, Arum, is already looking ahead to that potentially lucrative return, “If Horn beats this kid, we could do the Pacquiao rematch in the first part of 2018 or go right to a fight with [Terence] Crawford. Pacquiao might not fight again. Who knows?” he told ESPN earlier.
Corcoran, 26, has been described as a fringe contender, whose biggest fight came in July 2016, when he suffered his only career defeat in a British super-welterweight title showdown with bitter rival Liam Williams.
Managed by Frank Warren and trained by Frank Greaves at the Peacock Gym in London, he dropped down to welterweight after that sole loss and recently edged past Larry Ekundayo by split decision on July 8 to claim the vacant WBO Inter-Continental welterweight title.
Winning that belt placed him at no.10 in the WBO world rankings, seven spots below stable-mate Bradley Skeete, also signed with Warren, who many anticipated winning the shot at the world title.
ESPN will televise the fight in the United States, as part of their deal with Top Rank, with BoxNation TV likely to win the rights in the UK.
Horn’s selection for his first defence has been criticised by many but his pick of a top-10 ranked opponent with the same number of wins should make for a good contest. Even though “The Hornet” has one eye on a bigger fight in 2018 with either Crawford or Pacquiao.
Corcoran beat off WBO #10 Ray Robinson, #3 Bradley Skeete and #8 Luciano Veron to land the world title shot.
Stable-mate “Super” Skeete was considered the favourite to get the fight last week, one that he is been chasing for a few months now.
Arum favoured Corcoran’s style over other possible contenders, “Corcoran at least will bring the fight to Horn,” he said.
“We are clearing a location in Brisbane and once that is cleared then we can go ahead with doing the fight, which will now take place in December instead of November, which is what we were originally planning,” Arum said exclusively to ESPN that the fight will probably take place on Friday 15th December in Brisbane.
“We are waiting for the guys in Australia to finalise the plans for the stadium in the next day or two. They’re finishing that up and then we’ll send out the contracts, but everything is done with (Corcoran promoter) Frank (Warren) for the fight,” said Arum, adding that the Queensland government is heavily involved in bankrolling the fight, as it was when Horn faced Pacquiao in one of the biggest bouts in Australian history.
Horn won a debatable decision against Pacquiao on July 2 before a crowd of 51,000 at Suncorp Stadium in Brisbane in the first main event of Top Rank’s deal with ESPN.
Pacquiao, boxing’s only eight-division world champion, nearly knocked out the 29-year-old home fighter in the ninth-round but couldn’t put him away.
Most spectators thought Pacquiao, who had been bloodied by multiple cuts from accidental head-butts, was the clear winner. He wound up losing the fight and his 147-pound world title by a unanimous decision on scores of 117-111, 115-113 and 115-113.
Pacquiao had the right to an immediate rematch and said he planned to fight Horn again in November, but changed his mind because of a busy schedule with his day job in the Philippine Senate. He may return for the rematch in 2018, should the Aussie world champion get through his encounter with the English "Hellraiser" first.
