It appears the fight will be Nov 27th... which is... like tomorrow... it's still not in Boxrec but Cello said in his twitter he'll fight on Tuesday in London for "International Masters" title (what ever that is?) and couple of weeks ago this was published:
To me it seems the opponent is a Latvian journeyman who takes on pretty much anyone. As an opponent I guess he's ok for some one who has fought as little as Cello recently has. But in any kind of title fight I'm not so sure... so far he's had only 4 and 6 rounders in his 31 fights. I understood this was going to be 10 rounds.
