Part of the ‘fun’ for fans of combat sports has always been the fact that your theories about fantasy bouts can often be tested for real. Whether it is pairing fighters up from different MMA promotions, or different sports like boxing, if there is enough money involved it could happen.

McGregor vs. Mayweather has, of course, opened the floodgates to this sense of speculating that anyone can end up in the ring/octagon against anyone else. But it also caused bookmakers to open betting markets on these fights before they are anywhere near set in stone.

Below are some of the fights priced up by major bookmakers. Understandably, some are very much far-fetched in terms of the likelihood of them taking place. McGregor, as you might expect, features quite heavily. You can judge for yourself if the bookmakers have got the odds right:

Conor McGregor vs Khabib Nurmagomedov

There is, of course, a fair chance of this one taking place, providing McGregor puts his recent troubles behind him. It would pit UFC’s third-ranked pound for pound fighter McGregor against its current Lightweight champion and eighth-ranked fighter Nurmagomedov. It may surprise you to see McGregor as a 13/10 outsider with UK bookmaker Betway. Nurmagomedov can be found at odds of 8/13.

Conor McGregor vs Floyd Mayweather

The much talked about ‘rematch’ which would see McGregor and Mayweather clash under MMA rules. The odds suggest that it would be as one-sided as their boxing match, although this time McGregor is the overwhelming favourite. The Irishman is given odds of 1/10 to win, with Mayweather 5/1. Sky Bet have also released markets on the following: Mayweather to have official UFC fight in 2018 (2/1), Mayweather to fight McGregor in the Octagon in 2018 (4/1) and Mayweather to hold an official UFC belt in 2018 (33/1).

Jon Jones vs Brock Lesnar

There is still a lot of confusion over Brock Lesnar’s future, although a return to UFC does look likely. Jones is favoured to win any potential match, given odds of 2/7 to Lesnar’s 5/2. However, the bookmakers made a mistake in putting Lesnar as the underdog in the odds of his last return against Mark Hunt. Remember, while it is now deemed a no contest on Lesnar’s record, you could still have cashed your Lesnar money from the bookmakers on the night.

Stipe Miocic vs Anthony Joshua

This is by far the least likely to occur on this list, so you would imagine that it has been added simply as a novelty bet. Joshua, has a lot on his plate right now. The British boxer is aiming to unify all belts in the heavyweight division and has Deontay Wilder in his sights. Joshua is 4/7 favourite for that one (Wilder is 15/8). He is trying to build a brand in boxing and rejuvenate the heavyweight division, so you can be sure it will be a long time before he steps into the Octagon. The bookies have priced it hugely in favour of Miocic though, with the American-Croatian fighter priced at 1/50. Joshua is priced at 10/1. Save your money though, it won’t happen.
