According to The Scottish Sun, Celtic left-back Boli Bolingoli broke strict quarantine rules by secretly traveling to Spain before Sunday’s Scottish Premiership clash with Kilmarnock.

The Parkhead outfit weren’t aware that the Belgian had been out of the country until after the clash and have since launched an investigation.

The 25-year-old didn’t self-isolate upon returning from the high-risk country, coming off the bench to feature in the 1-1 draw.

While Bolingoli has since tested negative for Covid-19 and apologized, his action has left Celtic boss Neil Lennon raging, and he is likely to face the music.

Eight Aberdeen players breached the lockdown rules and visited a bar last week, with two testing positive for the coronavirus.

Their clash at the weekend was postponed with all the players now in self-isolation, and the action from the Celtic defender could force the Scottish government to halt the newly-resumed Premiership season.

Hoops legend Chris Sutton has been left fuming with Bolingoli, and here is how he has reacted on Twitter after hearing that he breached quarantine protocols:

There should be no way back for Bolingoli at Celtic now. If he knowingly went to Spain before the Kilmarnock game and broke quarantine rules he showed he really doesn’t give a sh## about his teammates, the manager and the support… Celtic should get rid immediately

That’s just terrific
