Carl Froch's Super Six World Boxing Classic fight with Dane Mikkel Kessler will take place on April 17.
The date of the super-middleweight showdown, which will take place in Denmark, was confirmed by Froch's promoter Mick Hennessy on Tuesday.
Hennessy said: "We've confirmed a date of April 17 for the Kessler fight. It will take place in Denmark and will be on at around 10pm in the evening UK time which is great news for British fight fans. It's going to be an absolutely massive event and it should attract a huge audience.
"It's an incredible fight between two of the world's best and most exciting fighters."
Froch, the reigning WBC super-middleweight champion, beat Andre Dirrell in his first contest in the 'Super Six' round-robin stage, while Kessler lost to Andre Ward.
Both men will have three fights in the six-man tournament before the top four in the league standings progress to the semi-finals. That means Kessler, a former victim of Joe Calzaghe, will be desperate for a victory in front of his home fans.
Hennessy, however, is confident his man will prevail.
He added: "Carl proved with that sensational KO over Jermain Taylor that he can go into the lions' den and beat the very best in the world and I've no doubt he'll prove that again against Kessler.
"Carl's been outstanding over the last 12 months. He's had three massive fights in a row against Jean Pascal to win the title, a sensational knockout against Jermain Taylor in the US to retain it and then opening his Super Six account by handing Andre Dirrell his first defeat.
"He's shown the kind of mental and physical toughness in those fights that I don't think any other British fighter in recent times has possessed."
Meanwhile, Froch, recently voted by the British Boxing Board of Control as their boxer of the year, is looking to build upon all the good things he has achieved over the past 12 months.
"Last year was great, this year's been fantastic and next year's going to be even better," promised the unbeaten 32-year-old.
