Waratahs fullback Israel Folau has been given the all-clear to join his NSW teammates in South Africa after he saw a specialist in Sydney on Thursday to check on his throat injury suffered in last Friday's win over the Melbourne Rebels.

He is hoping to fly out from Sydney to the Republic on Saturday with a view to joining the Waratahs in Durban where they will play the Sharks at Kings Park on Saturday (local time).

Due to swelling in the throat from a blow he received during the Waratahs 32-8 win over the Rebels at Allianz Stadium, Folau was unable to travel with the NSW team last Saturday. However, in Thursday's medical check, he was given the all clear.

Folau, who has scored eight tries from four games this season, has already spoken to Waratahs coach Michael Cheika about his return to the team.
