Fury famously exchanged serious fighting words with Wilder a few years ago in the ring.
In his latest Instagram video, Fury says that he will keep his promise and fight the current WBC World heavyweight champion.
“Guess who is back. The one and only. Shoutout to the Bronze Bomber, Deontay Wilder for giving me the motivation and saying I can’t do it and I’m finished. I’m coming back for you baby. I’m coming back for you. I’m gonna fill up that promise I made to you a few years ago. You what I’m talking about.
