I very much doubt it.

If you were Jim Jacobs in 88 and Tyson had just beaten Spinks for $20 million would you really go to the UFC for peanuts?

I think the highest they reckon they have paid anyone is $5 million but even that is hard to believe.

When Toney faced Couture Toney was paid $500,000 to Coutures $250,000. A faded boxer earnt twice than their biggest draw!

I dont think it would have happened until he was at the end of his career and the big money fights were drying up. Jacobs would never have risked his investment for peanuts.

Say Mike breaks a limb and is out for a couple of years rehabilitating. What earnings would you lose? You would need that figure to be at least matched which would have been astronomical.
