Warriors doctor John Mayhew collapsed after an exercise class in Auckland last night and is in an induced coma.
Mayhew was rushed to hospital but details of why he became unwell are not clear.
Mayhew, who was the All Blacks doctor for 15 years, on the sidelines for 131 tests, before spending most of the last decade at the Warriors, became an Officer of the NZ Order of Merit for his services to sports medicine in the New Years Honours List.
Mayhew has worked in squash, world cross championships and the Commonwealth Games team of 1990. He is on the board of Drug Free Sport New Zealand.
