Thank you Joe, thank you DC (Daniel Cormier). I think that toughness has been the tail of my career and pushing me beyond what my body physically able to do is sheer wit and will and toughness, and I am in absolutely pleasure to fight in front of my adopted hometown of Edmonton. And although I could not get the result I wanted, it was an absolutely pleasure to have my last professional fight and here Edmonton it is the last time I have put this on (his fighting glove) so to thank you Edmonton and thank you Joe."
