A cut over his left eye became infected and Henderson needed round the clock attention until the danger passed.
There was a further surprise when he got home to Invercargill and was told Manly rugby league coach Graham Lowe had been phoning to get him to swap codes with Matthew Ridge.
"I would have gone too but the injury stuffed that up," he recalled.
"But then I never would have got to captain the All Blacks where I have 100 per cent success compared to someone like Fitzy who only ran at 77 per cent," he laughed.
"And look at Richie, his winning percentage is higher but his side only beat Japan 54-6 last year."
The All Blacks do a good line in droll humour and with Eric Rush in the north and Paul Henderson in the south, they have those bases covered very neatly.
