iSelect Titans fullback William Zillman has suffered the frustration of having to wait another week before being available to play after his hamstring injury pulled up sore after training this week.
Zillman, who has missed the past three matches, was chosen in the provisional 18-man squad to take on the Panthers on Monday night but will be out for at least another match.
Winger Anthony Don, who had minor surgery on his compound dislocation of a finger, will be given until Sunday's training to check his fitness. If he is ruled out, Kalifa Faifai Loa will come onto the wing.
