Aquis Gold Coast Titans coach Neil Henry has decided to switch Greg Bird back to his regular lock position and will debut 22-year-old Cameron Cullen at five-eighth in Sunday’s clash with Cronulla Sharks at Remondis Stadium (2pm).

Tyrone Roberts will miss his second match with a minor knee injury and, after another outstanding performance for Burleigh Bears in the Intrust Super Cup, Cullen gets his chance to show his wares in NRL company after being bracketed with Bird last week in the lead-up to the Broncos derby, before Henry went with the experience of Bird.

“He put in another top performance for the Bears on the weekend and he deserves to get his debut against the Sharks,” Henry said.

The Titans have again announced an extended bench which includes co-captain William Zillman who successfully returned from injury (calf) on Sunday for Tweed Seagulls in the Intrust Super Cup and Eddy Pettybourne who came into the side against the Broncos and performed well. A final decision on the 17 will be made late in the week with a Sunday kick-off.

Prop David Shillington is recovering well from the hip-flexor but his fitness will be tested later in the week.
