Gary ‘Spike’ O’Sullivan will become mandatory of Daniel Jacobs if he beats Chris Eubank Jr in London on Saturday.

Jacobs retained the WBA middleweight championship of the World in stunning fashion, stopping former Andy Lee foe Peter ‘Kid Chocolate’ Quillin 1:35 of Round 1 on their title fight.

Jacobs was probably the 160lbs champion contenders would have most fancied prior to Saturday, but his destructive performance in the Battle of Brooklyn might shorten the list of fighters over eager to challenge the American.

A unification bout with Andy Lee, if the WBO champ retains his title by beating Billy Joe Saunders on December 19, might appeal, but if ‘Spike’ wins his World title eliminator against Eubank Jr he will be next in line for the champ.
