Wladimir Klitschko is set to make the next defence of his world heavyweight title against American Bryan Jennings.
The bout, scheduled for April 25 at Madison Square Garden in New York, will be the 38-year-old's first in America in seven years.
Klitschko, who holds three of the four major belts, said in a statement: "It will be a tough challenge but I am especially happy to be fighting in New York again."
Klitschko's fight against Jennings will represent his the 18th defence of his second reign as champion, and his first since stopping Bulgarian Kubrat Pulev in November.
Jennings only made his professional debut in 2010 and has won all 19 of his professional bouts, although he needed a split decision to edge Mike Perez in his last bout in July.
The Philadelphian will bid to become the second reigning American world heavyweight champion after Deontay Wilder's WBC title win over Bermane Stiverne at the weekend.
Floyd Mayweather and Manny Pacquiao may be moving closer to agreeing terms for a long-awaited bout.
The pair, who both beat Ricky Hatton before the Mancunian retired, have long been considered two of the best fighters of their generation but have never met in the ring.
However, that may be about to change after Pacquiao's agent Fred Sternburg hinted to BBC Sport that talks between them were progressing.
Sternburg denied that terms had already been agreed for a May showdown in Las Vegas, but added: "There is still a long way to go. At least the movement has been in a positive direction."
Mayweather, unbeaten after 47 professional fights, and Pacquiao, an eight-division world champion, have tried and failed in the past to reach an agreement, but with them now 37 and 36-years-old respectively there may not be too many chances left.

Amir Khan's plans to travel to America this weekend have been halted after his visa application was declined.
The 27-year-old was due to fly to Las Vegas to attend Floyd Mayweather's fight with Marcos Maidana on Saturday, and had used his Twitter account to advertise promotional duties he would be carrying out while there.
His bid to do so was thwarted, though, with the welterweight saying his visa application had been declined.
Visa to America was declined after i had it approved a week ago. Was looking forward to the fight. Means I'm still in England.
It was reported that Khan had asked Prime Minister David Cameron for assistance.
Khan has had difficulties travelling to America before. In 2010 he had to train in Canada after visa delays, while in 2011 he claimed he was held in Los Angeles customs for over two hours because he is a Muslim.
The Bolton fighter is eager to be present at Mayweather's rematch with Maidana, as he attempts to persuade the world's number-one pound-for-pounder boxer to give him a 2015 fight.
British boxer Amir Khan beat his American opponent Luis Collazo on points in Las Vegas and has now set his sights on a future bout with the unbeaten Floyd Mayweather.
The judges scored the fight 117-106, 119-104 and 119-104 in the Bolton boxer's favour leaving open the possibility of a future fight with Mayweather - who also won last night at the MGM Grand.
Khan, who is unlikely to fight the unbeaten boxer in September because it is close to the Muslim fasting period of Ramadan, said after his fight: "I really believe I have the style to trouble Floyd Mayweather."
