Unbeaten heavyweight Tyson Fury will fight WBA, IBF and WBO champion Wladimir Klitschko in Dusseldorf in October.
Fury, whose last bouts saw him stop Dereck Chisora and Christian Hammer, holds a 24-0 record while Ukrainian fighter Klitschko has not lost a fight for 11 years.
The 26-year-old’s promoters Hennessy Sports announced the 24 October clash through a statement on their official website.
The 6ft 9in fighter defended his European heavyweight title from Romania's Hammer on a technical decision back in February.
Klitschko, 39, last fought in Dusseldorf in March 2013, retaining his four current belts with a knockout victory over Jean-Marc Mormeck, and is 64-3 over a near 20-year career which has seen him beat the likes of Axel Schulz, Ruslan Chagaev and Tony Thompson.
The encounter with Fury in western Germany will be his 19th defence in his second reign as world champion.
