Zac Lomax has vowed not to change anything about his goal-kicking for the State of Origin decider, despite a costly performance in NSW's tight game-two loss.

It comes as Hudson Young tweaked his groin injury and joined Payne Haas (back) and Brian To'o (knee) on the sidelines at training on Thursday, though the Blues are confident Young will be fine for Origin III on July 9.
