Boli Bolingoli has been hit with a five game ban after flouting coronavirus protocols. Two of the five matches have been suspended pending any potential future breaches.
The defender took an unauthorised trip to Spain at the beginning of August, with his club and manager Neil Lennon unaware. The left-back did not quarantine on his return, breaking government rules on travel.
With the club unaware of his trip, the 25-year-old then risked exposing his Celtic team-mates and coaching staff to COVID-19 as he returned to training at Lennoxtown.
To make matters worse, Bolingoli then came off the bench in a 1-1 draw with Kilmarnock, spreading the risk to the Ayrshire club's players and staff.
