Tui played the game at Robina just days after the sudden death of his step father and was involved in an altercation with a fan who remonstrated with the team following the loss.
Uncapped scrumhalf Jake Gordon and loose forward Angus Cottrell have been called into the 30-man squad for their clash with the Springboks in Port Elizabeth on Sept. 30 and Argentina in Salta on Oct. 6.
Another loose forward, Pete Samu, misses the trip after suffering a knee injury in the Argentina match that will sideline him for four weeks.
