Manchester United coach Mark Dempsey has been identified as the staff member hospitalised in Perth.
United are currently on a pre-season tour of Australia and are due to play Perth Glory on Saturday.
Australian news channel 9 News reported that a male in his 50s was taken by ambulance to Royal Perth Hospital from the Crown Towers hotel, where the United squad are based. The Sun later reported that it was Dempsey.
Further reports in Australia then emerged claiming that the male is now stable, although Royal Perth Hospital are yet to officially confirm his condition.
