Danaher, a centre, was originally unavailable for the tournament but agreed to fly out after a telephone call from manager Noel Murphy.
Troy Coker, the Australian No 8, pulled a hamstring during training yesterday and could be out for the remainder of the tournament, according to his coach, Bob Dwyer.
He will definitely miss Wednesday's Group A match against Canada in Port Elizabeth, when his place will be taken by Tim Gavin. It is the latest in a run of injuries for the utility forward, who played in the two previous World Cups.
Dwyer said a decision on a possible replacement would only be made later. "We are not yet sure about the extent of the injury. He'll definitely not train for at least a week and it might be even longer. It's a big loss for us and a big disappointment for Troy and consequently the team too," Dwyer said.
Tonga will not appeal against the expulsion of flanker Feleti Mahoni from the tournament.
