Impending fatherhood has three first choice Blues players in doubt for the opening rounds of the Rebel Sports Super 14.

Two All Blacks, winger Joe Rokocoko, flanker Jerome Kaino and halfback Taniela Moa are all expecting their first child in mid to late February, when the Blues are on their early-season road trip.

Their first match is against the Western Force in Perth on February 13, the Bulls in Pretoria on February 21 and the Stormers in Cape Town on February 28.

Rokocoko, whose baby is due on February 24, confirmed he had ruled himself out of the two games in South Africa.
