"Probably 40 per cent [of the population] have these but don't know about them ... he would undergo minor surgery to correct that," Kara said yesterday.
While in South Africa, Weepu played against the Bulls and Lions — his condition was initially diagnosed as a migraine — and he played against the Cheetahs on his return to Auckland before a scan showed he had suffered a stroke to the left side of his brain.
The stroke caused Weepu to struggle with his speech. On the day he flew to South Africa, Weepu slurred his words like he was drunk for approximately two hours before the symptoms disappeared. He had also complained of headaches and nausea. The speech issue reappeared later in South Africa.
"You wouldn't know talking to him," Kara said. "It was only the fact that he felt his speech was slower and he had to think about his words before he was talking to other people which made us get a scan."
Bryn Hall has replaced Weepu for tomorrow's match against the Highlanders at Eden Park.
