Britian's Amir Khan and Kell Brook will face one another in a welterweight showdown on Feb. 19, 2022, promoters announced on Monday.
Promoters Boxxer said the long-awaited bout had been signed and confirmed after lengthy delays caused by the coronavirus pandemic.
Last week Ben Shalom, told ESPN the deal was close, and when signed off it would be become one of the biggest fights outside of the UK's heavyweight division.
The fight will be held at Manchester Arena and shown live on Sky Sports in the UK.
Brook (39-3, 27 KOs), 35, from Sheffield, and Khan (34-5, 21 KOs), 34, from Bolton, could not agree terms in 2016 when the welterweights both stepped up with middleweight for alternative fights.
Brook and Khan have suffered defeats in recent fights, and both will have been out of the ring for over a year come fight night.
