Finnish heavyweight Robert Helenius (25-1, 16 KOs) stopped giant Russian Evgeny Orlov tonight in Tallinn (Estonia). The fight was stopped after six rounds when Orlov refused to come out for round seven.

Orlov came in as a last minute sub last night when Brit Ian Lewison didn´t have permission to fight - but apparently flew to Tallinn anyway. Orlov is a big man, often around 300 lbs, and while out of shape he can still give anyone a hard night´s work and that is what happened tonight.

Cuban-Finnish light heavyweight Dayron Lester stopped one Deniss Paramovanin in one and Finnish light heavyweight champ Timo Laine TKO´d Dzianis Yahoranka in two.
