A leading Scottish public health professor has warned Celtic that more players could be forced to self-isolate after a positive Covid-19 test in the Parkhead squad.
The club confirmed on Sunday afternoon that one player had the virus in the round of testing that followed their return from their winter trip to Dubai.
And Dr Linda Bauld believes it's "astonishing" that the winter training camp even went ahead amid the current Covid-19 crisis.
Manager Neil Lennon and his assistant John Kennedy have justified the trip to the UAE, insisting the club were in constant dialogue with the SPFL and SFA joint response group, as well as the Scottish Government.
The unnamed player will be missing for Monday's home match against Hibs.
But Edinburgh-based Bauld believes more will have to sit out if protocols are followed correctly, given the virus' ability to spread on transport and the bubble environment in which the players were training in.
She tweeted: "I'd be very confident that any contacts including while travelling will be required to self-isolate, using existing definitions of a close contact.
"Plus the club needs to ensure that the player is isolating. That will protect others. Quite astonishing that they went to Dubai."
