All Blacks legend Beauden Barrett has already outlined his retirement plans, but Saturday's historic defeat against Wales has thrown another twist into his remarkable international career.
The 35-year-old captained New Zealand for the first time in his 149th Test appearance, only to suffer a humiliating 35-28 defeat in Cardiff.
Wales ended a 73-year wait for victory over the All Blacks, leaving Barrett with an afternoon he would rather forget.
It was a remarkable turnaround for a player who, just seven days earlier, had scored twice against Scotland.
Barrett appeared to be playing himself into Dave Rennie's World Cup plans. Now, the debate over his long-term future is back on the table.
Beauden Barrett's retirement decision
Barrett remains contracted to New Zealand Rugby until the end of 2027, with next year's Rugby World Cup in Australia firmly in his sights.
The two-time World Rugby Player of the Year has previously indicated that the tournament could provide the final chapter of his international career.
When signing his contract extension, Barrett made his commitment clear.
"It's a huge privilege to put on the black jersey and one I will never take for granted."
However, his hopes of a fourth World Cup appearance looked increasingly uncertain earlier this year.
Barrett was overlooked for six consecutive Tests under Rennie, with Ruben Love, Damian McKenzie and Richie Mo'unga all competing for places.
The veteran eventually forced his way back into contention, scoring against South Africa before producing two tries in the 43-21 victory over Scotland.
Rennie was full of praise following that performance.
"I know there are people out there thinking that he's past it, but he's in an environment here where we really value his experience."
Wales defeat raises fresh questions
Barrett's first Test as captain should have been another proud milestone.
Instead, it became one of the most painful afternoons of his international career.
The experienced full-back struggled to find his usual rhythm, with New Zealand's attack repeatedly frustrated by a stubborn Welsh defence.
Speaking after the defeat, Barrett admitted his side had wasted opportunities.
"It felt like a brick wall at times, so you have to give Wales credit."
The result does not change his retirement plans, but it adds another hurdle to his World Cup ambitions.
With younger players pushing for selection and competition fierce across the backline, Barrett knows his reputation alone will not guarantee him a place.
New Zealand face England at Twickenham next Saturday, giving the veteran another opportunity to respond.
For a player who has spent more than a decade tormenting international defences, the final chapter is proving anything but straightforward.
Barrett wants one last shot at World Cup glory. The question now is whether he can convince Rennie that he still deserves it.
