Hull KR’s Australian forward Justin Poore has announced his retirement with immediate effect, bringing the curtain down on a career that has seen him rack up 209 senior appearances on both sides of the world.

The 29-year-old former St George Illawarra and Parramatta Eels prop joined the Robins from Wakefield Trinity Wildcats at the start of the 2014 season but his campaign was cut short by a fractured knee cap suffered in the Easter Monday defeat by Catalans Dragons.

Despite undergoing surgery and an extensive rehabilitation programme, Poore has decided to hang up his boots and return home with his family.

“It’s never an easy call to make but I know it’s the right decision for me, my family and for the club as well,” Poore said.

“My knee has been responding well to treatment but the feedback from the medical staff is that I run the risk of damaging it further if I was to return.

“The contact might mean I would never be able to walk properly again and that’s not a risk I want to take.”

Poore, who made three State of Origin appearances for New South Wales in 2009, plans to continue a plumbing apprenticeship in Australia.

Hull KR chief executive Mike Smith said: “It’s always sad when a player decides to retire because of injury, particularly in Justin’s case as we know how hard he has worked to try to get back on the pitch next year.

“Although his injury has restricted his appearances for the club this season, he has been a true professional on and off the field and I’m sure the likes of James Green, Jordan Cox and some of our younger forwards will be better for the time they have had working with him.”
