Celtic had to play a patched up side against Hibernian on Monday night and almost pulled off a victory had it not been for a late equaliser which was poorly defended.
Stephen Welsh was one of the players on the field because of the 13 of his teammates were home isolating.
The Celtic defender revealed the positive case sent panic around the players and it happened very fast.
Welsh describes things as business as usual before the call came through and panic set in.
Jullien testing positive then spending time with his team-mates in close quarters (something which wouldn’t have happened if the club were in Scotland) made it impossible that Celtic would continue unaffected.
Speaking to SunSport, Welsh describes the moment things changed and waiting for the dreaded phone call.
“It all happened very quickly. For everyone, there was a bit of panic because anyone can get it these days.
“You’re just hoping you don’t get the phone call to tell you you’re positive.
“I was happy I wasn’t one of the guys involved so I could play.
“Everything was normal, then we found out about the positive case and it happened really quickly.
“This is the first time since June or July, when we started testing, that someone has picked up a positive case within the club.
“You never think it’s going to be you, so when it happens it is bit of a shock.”
Celtic now go into the Livingston game this weekend without their first team players again.
Welsh will likely get the nod and we have to hope they can grab a win somehow. At this point, we’re at the damage limitation stage.
There’s a very real possibility Celtic could end so far behind first place it will be seen as the biggest one season implosion in Scottish football history.
