The Sergei Ignatiev that will be fighting Arona next weekend at Pride is the well known one from the Judo world.
He's a bit past his prime (He was born in 1971) but he was a solid international level Judo player.
Past accomplishments include:
2002 - Minsk-A 2nd 90kg
2000 - Kano Cup 7th
1996 - Moscow-A 3rd
1996 - German-A 3rd
And a whole slew of other bronzes at various A-levels.
Does anyone know if this is going to be his first MMA fight?
