Three instantly spring to mind... Lewis v Rahman Honeyghan v Curry Khan v Prescott (China chin or not that was a massive upset) They are all pretty high profile any domestic bust-ups or lesser fights that were considered mammoth upsets?
SRR-Turpin Benn-Gman Fitzsimmons-Corbett? Buchanan-Laguna? No idea if the last two were massive upsets tbh
Enzo Macc against Ola Aflobai Aflobai was considered a sparring partner with a low KO ratio He was 9/1 against the win - which is big odds in a two horse race
Wasn't he around 20/1? I seem to remember him being the same odds as Buster Douglas was that night against Tyson?
Lewis Rahman and Khan Prescott - NO Honeyghan Curry - Very much so. Except Honeyghan was really good.
