Rewind eighteen months and the conversation about Walker was a worried one. An ACL rupture, compounded by a thumb injury, cost him 314 days. That is not a layoff, that is an absence long enough for a competition to move on without you. His comeback game against St George Illawarra was exactly what a comeback game looks like, a forward pass, six missed tackles, a sin-binning for a cannonball tackle on David Klemmer, and then, because he is who he is, a field goal and a try assist that swung the result. Rusty and decisive in the same eighty minutes. Very Walker.

What followed in 2026 was the payoff. Paired with Daly Cherry-Evans, Walker stopped being the Roosters’ promising kid and became their organising intelligence. The partnership gave Trent Robinson something he had lacked for years, a halves combination where one man could freelance because the other held the structure. Walker drove a six-game winning streak, hauled the Roosters into premiership contention, and did it playing the improvisational, faintly chaotic football that he is renowned for.

Then came Origin. Billy Slater handed him the Queensland No. 7 and the Langer comparisons wrote themselves, another undersized, instinctive Ipswich junior out of Norths Tigers, another halfback whose best work happens in the half-second after the plan breaks down. Walker shone on debut. By August, Robinson was publicly arguing that his halfback would one day be rated above Nathan Cleary. That is not a throwaway line from a coach given to hyperbole. Robinson does not do hyperbole.

But now, we won’t be able to see what he can deliver in Septembet. The ankle went early in the second half against the Dolphins. He left the ground in a moon boot, had scans late that night, and by Sunday the worst case had been confirmed, a syndesmosis injury and his season over. Cherry-Evans is expected to shift back to No. 7, which is a solution rather than a replacement.

The disappointment is not simply that the Roosters lost a good player at a bad time. It is that Walker had spent a year answering every question anyone had about him, durability, temperament, whether the flair survives at Origin level, and was three weeks from the only exam that counts. He gets no grade. The comeback story was complete except for the ending, and the ending is the part everyone remembers.

He is twenty-four. There will be other Septembers. This one deserved to be his.
