Brian To'o might be short in stature but the NSW winger isn't fazed about marking towering Queensland winger Selwyn Cobbo in next Wednesday's State of Origin series opener.

The Blues hit the training ground on Tuesday in Coogee with To'o lining up on the left side and Sydney Roosters winger Daniel Tupou on the other flank.
