COLLINGWOOD doctor Chris Bradshaw has been suspended by the Australian Health Practitioner Regulation Agency.
The matter doesn't relate to his work at the football club.
The leading sports medico has been stood down from his duties at the Magpies pending further developments.
A spokesperson for the Medical Board of Australia confirmed Dr Bradshaw’s registration had been suspended on Monday, with the doctor reprimanded under section 191(3)(c).
The AHPRA would not provide any further details around the suspension.
"Collingwood is aware of, but not involved in, a matter pertaining to Dr Chris Bradshaw and the Australian Health Practitioner Regulation Agency," Collingwood said in a statement.
"Chris will not be fulfilling his role as Collingwood physician in charge while this matter proceeds.
"Collingwood is not in a position to make any further comment."
Bradshaw is one of the most respected doctors involved in Australian football.
Having first worked at Melbourne, Bradshaw was then at Richmond from 1991 until 2004 when he headed to London to become head doctor at English Premier League club Fulham.
He returned to Australia two years later and served for nine years as chief medico at Geelong before moving to Collingwood at the end of 2014.
