What happens to my bet when Daniel Cormier withdraws?

I made a futures bet taking Daniel Cormier to win against Jon Jones on April 23, however, Daniel Cormier pulls out due to an injury. What will happen to my bet now? Do I lose my bet because Daniel withdrew? Do I get my bet back? Any information would be greatly appreciated.

A replacement fighter by the name of Ovince Saint Preux will be fighting in place of Daniel Cormier. Or will my money now be on Ovince Saint Preux? I hope not.

DonDiego opines that if a fighter is replaced all bets are cancelled. The odds on each fighter would need to be recalculated before wagering could resume.

bet365.com states:
"If either fighter is replaced with another fighter all bets will be void and stakes returned."

As always one is advised not to take anything which poor old DonDiego says as Gospel
