David Haye and Tyson Fury will today end weeks of Twitter trash-talking when they share the stage to announce their domestic heavyweight showdown in September.

Haye returned from retirement this year with a view to fighting Manuel Charr last month but after that was postponed due to a hand injury, talk turned to a grudge match with Fury.

Haye is not the first man to have become rattled by the outspoken Fury, who despite his lack of experience at the top level, wanted two-time world champion Haye to agree an 80-20 purse split in his favour because he claimed the 32-year-old had seen better days.

Middle ground does seem to have been found, though, and the two men will today confirm a 28 September date in Manchester when they meet at a press conference in London.

The announcement of the media call came a day after Haye posted a video on social media sites purporting to show him signing a contract for the hotly-anticipated contest.

Fury did not comment on Haye's claims initially but entered into more social media warfare last night, telling his opponent he would "need a shotgun" to beat him.

The joint statement read: "David Haye and Tyson Fury, both world-ranked, charismatic and dangerous, have agreed to a highly-anticipated domestic showdown on Saturday September 28 at the Manchester Arena.

"It marks not only the biggest heavyweight encounter of 2013, but also the biggest fight staged in Britain for many years."

Haye bounced back from his world title defeat to Wladimir Klitschko in 2011 with a fifth-round stoppage win over another domestic rival, Dereck Chisora, in London last July.

Fury has won all 21 of his professional contests to date, most recently a seventh-round stoppage of American Steve Cunningham in April.
