Dillian Whyte and Robert Helenius will meet for the WBC silver heavyweight title at the Principality Stadium in Cardiff on Oct. 28.
Whyte is hoping victory over Helenius on the undercard of Anthony Joshua's world-title fight with Kubrat Pulev can put him on the path towards a possible world-title fight of his own with WBC champion Deontay Wilder.
"It's been a very frustrating few months trying to get someone to fight me," Whyte told Matchroom Boxing.
"I thank Robert for stepping up and in two weeks' time we will fight for the WBC silver title in Cardiff.
"I love to fight and I'm looking forward to being back in the ring, getting the victory and moving on to challenge for the World Heavyweight title."
The 33-year-old Finn, known as 'The Nordic Nightmare', is delighted to have landed the fight and said: "This is a huge fight and I'm excited about fighting the winner of last December's thriller between Whyte and [Dereck] Chisora."
"Chisora and I were scheduled to fight in May but he ran. To my understanding Dillian is not a runner and he will stand and fight. This is a big fight for the heavyweight division and may the best man win."
