As reported in The Scottish Sun, Brown mistakenly liked a post on Twitter criticising Lennon’s team selection against CFR Cluj in the Champions League qualifiers last week.
The 34-year-old former Scotland international midfielder - who has been on the books of the Bhoys since the summer of 2007 when he joined from Hibernian for a transfer fee reported by The Guardian to be worth £4.4 million - subsequently apologised for accidentally liking the tweet.
Celtic boss Lennon has given his take on the gaffe from the club captain, and while he has laughed if off, he has suggested that it can be a “damaging” for the former Hibernian star if he is on social media too much.
Lennon told The Scottish Sun: “Scott’s never been the brightest! Seemingly he’s accidentally hit this like button.
“I don’t think he’s ever been on Twitter that much. He was just looking for the reaction, which is natural.
“It can be damaging. Maybe he can detach himself from it as well and concentrate on being the great captain that he is.”
The Celtic players and fans will be bitterly disappointed at the exit from the Champions League qualifiers, but they need to move on now.
The Glasgow giants will hope to negotiate the Europa League playoff round and book their place in the group stage for the 2019-20 campaign.
