Brook, 26, was due to challenge 25 year-old two-weight world title holder Alexander on February 23rd in Detroit, Michigan until a bicep injury ruled the American out and Golden Boy are soon to announce a new date.
The Matchroom promoter has been busy dealing with the official announcement for the big super-middleweight title unification all day, but took time out to speak to WBN and wants to keep positive as he awaits the rescheduling for Brook’s first world title tilt.
“It’s bitterley disappointing but that’s boxing,” Hearn told World Boxing News.
“We are waiting for a new date which we hope to get this week. They key now is to keep Kell focused, upbeat and ready for whatever date we are given.”
The rest of the card will go ahead as planned in two weeks’ time as home fighter Cornelius ‘K9’ Bundrage tops in his native city for the first time since 2005 against Ishe ‘Sugar Shay’ Smith, with J’Leon Love as chief support.
