The bout, which Brook earned by defeating Hector Saldivia in a final eliminator on October 20 in his home town of Sheffield, was initially pencilled in for January 19th.
But after suffering a minor ankle injury during early training for the title fight, Brook’s representatives requested and were subsequently granted a change of date to give him adequate time to return to 100%.
Brook, undefeated in 29 bouts with 19 knockouts to his name, confirmed the new official date via his Twitter account, saying: “Feb 23 I’m gonna show the world just how Special I am. I’m gonna bring this World title home for Britain.”
Alexander is 24-1 with 13 wins coming inside the set distance,and will be making his first defence after winning the belt from Randall Bailey in New York the same night as Brook’s third-round stoppage of Argentina’s Saldivia.
