Lucas Browne only got paid 100k for his fight. Very dodgy referee in which in round 6 (when he got knock down) the round went 15 sec longer and in round 7 it went 44 sec shorter. In the end he won by TKO in round 10. This is massive achievement as he was fighting abroad in Cheznya.

McGroggy on the other hand, got massive payout of 1M for his lost to Diaz (500k).
UFC is so good in promoting fights and getting the gate numbers.
