Actually I have heard of him, although I don't recall watching a whole fight, I remember being impressed with him: fast hands, throws combinations, very athletic looking, surprisingly big kid (listed at 6'5").
Here's a nice KO compilation from youtube for anybody interested

although granted I assume all of his opposition is probably very limited. Still looks like a fun addition to HW if moved right. I'm interested.
I personally don't rate Hughie at all and I can't see the Fury camp taking this, what with all the current family turmoil.
