The fighter purses for Miguel Cotto and Canelo Alvarez have been released publicly. Even though Canelo is pegged to be the next top draw in boxing, he'll only receive 25% of the $20 million split between him and his foe after Saturday night. However, according to ESPN's Dan Rafael, there's more to it for both men, particularly for Alvarez.
Official purses for #CottoCanelo per NSAC: Cotto $15M, Canelo $5M. Both can make more on upside, Canelo likely getting more via Mexico TV.
