Genia denies he's underdone for Ireland

Wallabies halfback Will Genia has laughed off suggestions he'll be underdone in his injury return against Ireland.

Genia, who missed the last month of Super Rugby with a medial knee strain, says he'll be 100 per cent ready to perform if selected on Saturday night at Suncorp Stadium.

The attacking linchpin labelled the Wallabies the worst disciplined team in world rugby and stressed they must turn that around to beat the Six Nations champions.
