The 25-year-old fullback has signed with the Dolphins from next season, but will spend the remainder of the year with the Titans where he adds depth at the back for the emerging side.

Titans’ coach Justin Holbrook said Isaako’s experience at NRL and international level made him a huge addition.

“He adds great depth to our outside backs and provides us with coverage across both the fullback and wing positions,” he said.

“We’ve got strong competition across a number of positions and adding Jamayne gives us another exciting option to choose from in our backline.

“With a number of talented young backline players on our roster, Jamayne will no doubt be able to help with their development during his time with the Titans.”

Isaako provides strong backline cover for the Titans with 22-year-old Jayden Campbell the starting at fullback.

The Broncos confirmed his departure on Tuesday morning.

“The Broncos were happy to facilitate the request and wish Jamayne and his young family all the best in the future, both on and off the field,” a club statement read.

Isaako has made 77 appearances for the Broncos, scoring 24 tries.

He started Brisbane’s round one win against South Sydney at fullback before Tesi Niu took over in the No.1 jersey in round two.

It had been speculated Isaako would join the Eels for the remainder of the season before starting his contract at the NRL’s new Redcliffe-based club.

The Eels remain one backline injury away from relying on their reserve graders, with Sean Russell, Maika Sivo and Haze Dunster all sidelined.
