Nope, I hadn't either but a tweet from Rick Hatton would suggest he's under his management or at least tutelage. 21-0 with 19 KO's but not a name on his record at first glance.
He's apparently the WBA's mandatory, looks as though he picked up some trinket a fight or two ago to get in to this position...
looked him up on Boxrec... turns out he's the Belarussian poor man's Gary Cornish, and ranked at #230 according to BR
Who? Hopefully not worse than boring Sergey Rabchenko who got rogered by Old Man Choc down under a couple of years ago.
