The Bhoys captain apologised after receiving his marching orders in the Champions League
The Scotland international received his marching orders early in the second half of the Hoops’ key Group H encounter after clashing with Barcelona forward Neymar.
Neil Lennon subsequently came out in support of Brown, pointing the blame at the actions and reactions of the Brazilian and his Catalan teammates.
However speaking in an exclusive interview with the official Celtic website earlier today, the Bhoys captain offered an unreserved apology for his actions.
"I realise that I made a mistake in getting sent off last night. It´s something that happened in the heat of the moment but I shouldn´t have acted in this way,” he said.
And while Brown admitted that his actions left Celtic in an extremely difficult position for the remainder of the tie, he was keen to note that he thought the referee made a “harsh decision” in sending him off.
"There wasn´t a huge amount of contact at all, to be honest, but I have to accept responsibility for my actions – and I do,” he noted.
The defeat has left Celtic bottom of the table and without a point from the two games played with crucial back-to-back fixtures against Ajax to come.
Frank De Boer’s team were unlucky to draw with AC Milan at the Amsterdam Arena last night, conceding a controversial last-minute penalty which was won and duly dispatched by Mario Balotelli.
The draw nevertheless offers Celtic a glimmer of hope going into the next two games, though if the Bhoys are to stand any chance of advancing to the knock-out stages they will need to pick up a minimum of four points from the six available.
Neil Lennon’s team are next in action against Motherwell at the weekend.
