Gold Coast star Mat Rogers has been ruled out of tomorrow night's clash with the New Zealand Warriors in Auckland due to a troublesome knee injury.
Utility Luke O'Dwyer will shift from the forwards into the centres to replace Rogers while former Super 14 rugby player Josh Graham will cover lock.
Titans coach John Cartwright says he doesn't want to risk dual international Rogers in the greasy conditions at Mount Smart Stadium.
The Titans snapped a five-match losing streak with a 30-14 win over Wests Tigers last weekend while the Warriors have recorded six wins and a draw over the past eight weeks.
Fittler has helped the Roosters to three wins and a draw since taking over from Chris Anderson and they can move just one point outside the top eight with a win over the eighth-placed Tigers.
Skipper Craig Fitzgibbon will miss the match with an ankle injury with Nate Myles coming into the starting line-up in his place. Tonight's other match pits high-flying Manly against the troubled Newcastle Knights at Bluetongue Stadium on the Central Coast.
Meanwhile, Newcastle coach Brian Smith insists he is just following orders and is not to blame for overseeing a wholesale cleanout at the Knights.
Injured captain Danny Buderus claimed the club's decision to show a host of long-serving players the door had left player morale at an all-time low. But Smith claims the decision to overhaul the roster was made long before his arrival with the club looking to move forward in the post Andrew Johns era.
