Anthony Joshua and Joseph Parker faced off for the first time after a tense press conference in London on Monday. The heavyweights met for the first time at the Dorchester Hotel in what was a feisty encounter between the champions and their promoters.
Joshua holds the World Boxing Association and the International Boxing Federation titles, while Parker holds the World Boxing Organization title and has not lost in 24 games and won 18 of them by knockout.
In a recording on Twitter , Joshua, 28, confirmed the match.
"These games are not easy because they have a lot to do, and all the respect for Parker to accept the challenge and you know me, I love this game," Joshua said.
"I am eagerly waiting for this confrontation and I am continuing in a training camp, our date is 31 March."
The winner will take a step closer to becoming the first undisputed heavyweight champion since Lennox Lewis in 1999.
American Deontay Wilder holds the fourth heavyweight belt (WBC).
