Anthony Joshua returns to the ring for his eagerly-anticipated match-up against former cruiserweight king and now heavyweight enigma Oleksandr Usyk later in September.
The IBF, WBA and WBO champion puts his belts on the line against the undefeated Ukrainian, who will fight for the third time at heavyweight, after defeating Chazz Witherspoon and most recently Derek Chisora.
Joshua put in a scintillating performance in his previous outing against the ever-tough Kubrat Pulev, mixing his new back-foot style with the old hard-hitting, spiteful puncher we'd previously become accustomed to as he claimed a ninth-round stoppage win.
The 30-year-old had appeared nailed on to take on rival Tyson Fury for the all of the belts in one of, if not the, biggest fight in British history.
But with an American arbitrator ruling Fury must take on Wilder for a third time instead, a bout taking place in October, Joshua now looks to take care of his WBO mandatory challenger.
Though Usyk's capabilities at heavyweight are still somewhat of an unknown, it's a match-up that has generated significant interest in what could be a seriously dangerous fight for the Brit.
With the match-up now swiftly approaching, Sportsmail takes you through everything you need to know.
