In December of last year, Tony Bellew promised to end the career of David Haye - and then he also promised to end the career of Tyson Fury.
Back on May 5, in their highly anticipated rematch, Bellew blew Haye out in a one-sided contest. Bellew put him down three times for a fifth round stoppage at the O2 Arena in London.
And last week, Haye announced his retirement from the sport.
One down, and now one to go.
"I now have a very clear plan for 2018 and that is to knock out David Haye and then knock out Tyson Fury and end both their careers but first things first I need to rid the sport of David Haye on May 5," Bellew said a few months ago.
And then last weekend in Manchester, Fury made his return after being inactive since his victory over Wladimir Klitschko in November of 2015.
Fury picked up a one-sided stoppage win over Sefer Seferi - in a contest where many critics ridiculed the level of opposition. Seferi was not competitive and appeared to quit after four rounds.
Following the fight, Bellew challenged Fury to a 2018 showdown.
But the 6'9 Fury believes that he's too big and too strong for Bellew - who moved up last year from the cruiserweight ranks.
Haye was scheduled to fight Fury on two occasions, but withdrew both times with injuries.
He likes the idea of a Fury-Bellew showdown and feels the contest would be competitive - because he doesn't believe Fury is still the same fighter who shocked Klitschko.
“I would like to see Bellew in there with Fury, I think that would be a great fight. Bellew has proved his credentials at heavyweight by beating me twice when no-one really gave him a shot," Haye told The Sun.
“I don’t believe Fury is the man of old. I believe the Tyson Fury that beat Wladimir Klitschko would handle Bellew pretty easily but I’m not sure that guy will ever be seen again.”
