Connah's Quay Nomads manager Andy Morrison said he had to "turn a blind eye" to players who showed up unwell for Thursday's Europa League game against Dinamo Tbilisi as he had already lost four members of the squad due to COVID-19.
Three players had to be withdrawn prior to the second round qualifier after testing positive for COVID-19 while a fourth showed symptoms and was excluded as a precaution.
"Three lads have turned up tonight and they're not well," Morrison told British media after the Welsh champions' 1-0 defeat at the Racecourse Ground.
"And it's like, 'Lads I don't want to hear it. I can't hear it tonight that you're ill. ... Let's just get through it'.
"I've been told that before the game and we've had to turn a blind eye to it and then you would have never noticed that anyone there tonight wasn't feeling great."
