Nathan Cleverly will defend his WBO light-heavyweight title against Robin Krasniqi on 16 March.
No venue has yet been set but Cleverly's promoter, Frank Warren, has won the purse bid to stage the bout.
Cleverly would prefer it to be in Cardiff but the Welshman, 25, has said he would be willing to face Krasniqi in Germany, where the Kosovan is based.
The WBO threatened to strip Cleverly of his belt unless a bout with mandatory challenger Krasniqi, 25, was arranged.
Cleverly was due to meet Krasniqi in April 2012, but had to pull out with illness.
He hopes an impressive win over the twice-beaten challenger will open the way for unification fights in 2013, with WBA champion Beibut Shumenov one potential opponent.
Another option would be a bout with the winner of the fight between IBF champion Tovaris Cloud and Bernard Hopkins, who meet on 9 March.
"I think if the fight is in Germany, where it is notorious that the fighters get home decisions, I feel I'll really have to go out there and perform and put this guy to the sword," said unbeaten Cleverly.
"I've got to perform and impress against this guy and that's going to set up the rest of 2013 then for the big unification fights... Everything will fall into place after this fight.
"If it all goes well with the Krasniqi fight, Shumenov is definitely in my sights and I would definitely like to fight the winner of Hopkins and Tovaris Cloud."
Wladimir Klitschko's next opponent looks likely to be Russian heavyweight Alexander Povetkin.
Klitschko, 36, is WBA "super champion" and the governing body has enforced a rule meaning Povetkin, their "regular champion", must face the Ukrainian.
The bout must take place before February 26, 18 months since Klitschko overcame David Haye in Hamburg.
"We are very excited that Povetkin will be Klitschko's next opponent," said Povetkin's promoter Kalle Sauerland.
Klitschko is the WBA, IBF, WBO and IBO world heavyweight champion. His last contest was a 12-round points victory over Poland's Mariusz Wach in November.
Povetkin, 33, beat former champion Ruslan Chagaev in August 2011, a victory that set up a 2013 bout against Klitschko.
In his last fight, in September, he knocked out Hasim Rahman, the American who defeated reigning heavyweight champion Lennox Lewis in Gauteng in April 2001.
"We consider Wladimir Klitschko to be a great champion but we also consider Alexander Povetkin to be a very serious challenger," Sauerland added. "[This] will turn out to be a real treat for boxing fans all over the world."
Martin Murray says he will be fighting the "best middleweight on the planet" when he faces Argentina's Sergio Martinez for the WBC title on 27 April.
But the 30-year-old from St Helens, who is unbeaten in 26 bouts, believes he can cause an upset in Buenos Aires.
He told BBC Radio Merseyside: "He's very experienced and he's a very good fighter. He's won 50 and lost two.
"He's world class and I rate him very highly, but I know I can go over there and we know we can do him."
Murray added: "We know it's going to be a hard fight because everything is going to be against us, but we are quietly confident that we can do a job on him.
"We are confident that, one way or another, we will find a way to win."
Martinez, who was voted Argentina's sport personality of the year ahead of goal record-breaking footballer Lionel Messi, will be making his first defence since beating Mexican Julio Cesar Chavez Jr in Las Vegas in September.
