Brisbane winger Jordan Kahu says he may have to miss New Zealand's end-of-season Rugby League World Cup due to groin surgery.
Kahu says he will be able to nurse the injury through Brisbane's NRL title tilt and retain goal kicking duties ahead of Friday night's knockout semi-final against Penrith at Suncorp Stadium.
But Kahu may have to skip the World Cup starting in late October if scans indicate he needs to go under the knife.
"I still have to have scans but it is looking that way," Kahu said of end of season surgery.
"It is pretty sore but being this time of the year it is just something I push to the back of my mind."
Kahu may be considered for fullback against ex-Broncos coach Anthony Griffin's Panthers with Brisbane still sweating on skipper Darius Boyd's hamstring.
Boyd missed their tight opening finals loss to Sydney Roosters and is racing the clock to be fit for the knockout clash with Penrith.
David Mead filled in at fullback against the Roosters but a backline reshuffle may be on the cards to help keep Brisbane's title tilt alive.
Kahu admitted Brisbane faced a tough call on whether to roll the dice with Boyd's fitness.
"It's a hard thing. If we win this game and he does play and he gets hurt we miss him for the rest of the year, so we will see," he said.
"He is a crucial player, our team captain and we would love to have him back - it will be a tough decision."
Kahu backed himself to retain goal kicking duties despite nursing his groin complaint.
The Kiwi international admitted he would have to wait until match eve to practice his goal kicks but didn't believe that would be a problem.
"Personally I just want that job. I want to be able to take those big kicks in the finals," he said.
