Midfielder Alex Gogic has confirmed he was the Hibernian player who returned a false positive test for Covid-19.
After routine testing on Friday, Hibs called off Saturday’s training session when the Cypriot received his results.
Further tests were negative, but the player will self-isolate for 10 days, which means he will miss his first international call-up.
Hibs, who said he “strictly followed all protocols”, lost 1-0 at home to Aberdeen on Sunday.
Head coach Jack Ross said Gogic having to self-isolate is “frustrating” given he has been given the green light.
“I have been very respectful of what we have to adhere to and I am not going to change that,” he told BBC Scotland.
“But applying common sense to it, I struggle a bit. This may have highlighted flaws that could be fixed. ”
Ross has also confirmed that he expects winger Darryl Horgan to leave the club for England in the coming days.
