its possible if it stays stand up, he was a kickboxing champ at one point, and a few people have proven age in the 40s isnt a big factor anymore ( cotour and lesnar fight)
will he win, probably not, but hopefully he doesn't bitch out
itd be smarter for him to just go back into a kickboxing tournament over in europe or something and stay away from MMA, since it includes a lot more than just stand up
