Bolingoli broke lockdown rules before Killie match

Celtic defender Boli Bolingoli didn’t tell club chiefs he’d been to a high-risk country – and didn’t isolate – then played against Kilmarnock. He has since tested negative.

The defender, said: “I have made a huge mistake. I want to apologise to my Manager, my teammates, the supporters, everyone at Celtic and so many others for letting them down so badly.

“I am guilty of a major error of judgement. I know what I did was wrong and I know that I must now deal with the consequences.”

A spokesman said: “Celtic Football Club has taken its response to Covid-19 extremely seriously and we are pleased that, to date, we have recorded no positive tests.

“Our staff have given so much in this area, working tirelessly to ensure that all players and other club personnel are safe, fully aware of their own responsibilities and familiar with all guidance and protocols.

“Safety must always be our priority.

“Clearly, a full investigation will now take place and the Club will take all appropriate action.

“Subsequent to the player’s return he has recorded two negative tests in the past week.”
