I don't think there's much you could have done. If he was so adamant about continuing, then that's going to be what happens. Probably the only persons who could have "forced" him to sit would have been the assignor or the tournament director. Your "authority" was only to the extent of trying to convince him you could have handled the game by yourself, or somehow gotten a last minute replacement. You just have to do the best you can out on the court to "cover" for him.
