This has sort of been brought up in the past, the answer is no.
More speficially, from the site FAQs:
If a fight is declared a draw or no contest at the time of the fight, this bout will simply not be calculated into the points, ranking, or earnings. The result and scoring from a fight that is overturned at a later date (steroids, Mary-J, etc) will remain on the website. Asking someone to send back their per-event prize so that we can send it to someone else due to a scoring change isn't something we're up for. Plan and play accordingly! This game is based on who wins at the time of the fight.
