Verified Thank you all so much for all your messages of support all week. I have been blessed on this journey in MMA and am truly grateful for every experience. I felt great all through camp and even warming up, I believed I was back to my former self then when I went in there it just falls to pieces. I think it\u2019s time to realize that I haven\u2019t got what it takes any more. Congrats to Joel Alvarez and thank you to the UFC for all the opportunities. I\u2019m sorry I didn\u2019t achieve what I set out to achieve for my fans, family, friends and myself but it just wasn\u2019t meant to be. I am officially retiring from MMA competition 👊🏻 https:\/\/www.instagram.com\/p\/CCzXhUFHb1z\/?utm_sourceig_embed Duffy puts an end to a once-promising career including a submission victory over former two-division champion Connor McGregor.
