It was Piri Weepu's speech problems while with the Blues in South Africa that prompted the scan that revealed he had played three matches after suffering a minor stroke.
Weepu is expected to make a full recovery from the stroke he is believed to have had on March 1, the day after he played the Crusaders at Eden Park and the day the team flew to South Africa for matches against the Bulls and Lions - both of which he played in. He also played in the victory over the Cheetahs at Eden Park last Saturday but now faces a spell out of the game of four weeks at least.
The stroke - which caused Weepu to slur his words "like he was drunk", according to Blues doctor Stephen Kara - was initially diagnosed as a migraine by Kara and a specialist, but it was the halfback's continued issues with his speech in South Africa which raised alarm bells.
"He did say to me that he felt his speech was a bit slower and that he had some difficulty finding words or articulating words and he had to think about the language that he used," said Kara, who added that, at 30, Weepu was not a prime candidate for a stroke.
