Even Gold Coast coach Neil Henry admits it is crazy that John Olive will be making his Titans debut just days after lobbing at the NRL club.

Former South Sydney flyer Olive has been rushed into a reshuffled Titans backline for Sunday’s season opener against Newcastle after Titans co-captain Will Zillman succumbed to a calf injury.

Days after training with the Titans for the first time, Olive was slotted onto the wing for the NRL clash after David Mead moved to fullback for Zillman.

Henry did not rule out more late arrivals after confirming Zillman would not be risked against a new look Knights.

“It is a bit crazy the way the rules allow that to happen with late movement,” he said.

“And I think there will still be a bit more movement in the market before June – but that’s what it is.”

Henry opted for the 19-year-old Olive – who has been signed until the end of the 2018 season – over Leva Li for the wing vacancy.

Olive only arrived on the tourist strip earlier this week to answer a backline SOS from the Titans.

Olive had already signed a two season deal with the Gold Coast from 2017 but earned a South Sydney release a year early to add much-needed depth to the Titans backs.

The injury setback was another blow for Zillman who had not played an NRL match since round 10 last year due to a back complaint which required surgery.

“He (Zillman) could play at a pinch but getting out 80 minutes would be a real risk for him,” said Henry.

Hooker Nathan Friend will lead out the Titans on Sunday.
