Wladimir Klitschko vs. Tyson Fury, billed as Kollisionskurs (German for "Collision Course"), was a professional boxing match contested for the WBA (Super), WBO, IBF, IBO, The Ring magazine, and lineal heavyweight titles. The fight took place on November 27, 2015 at Esprit Arena, Düsseldorf, Nordrhein-Westfalen, Germany. Fury was declared the winner by unanimous decision. This ended Klitschko's reign of nearly 10 years, the second longest in heavyweight history. Klitschko was entitled to a rematch per the fight contract. Despite this, Fury was stripped of the IBF heavyweight title for agreeing to the rematch instead of facing the IBF mandatory challenger, Vyacheslav Glazkov.
