A football fan leapt into the Celtic dugout during a match to take a selfie with manager Neil Lennon.
Connor Dempsey climbed over the barricades and attempted to approach the Irishman on October 3, 2019.
The drunk 24-year-old was stopped by officers and arrested.
He pleaded guilty at Glasgow Sheriff Court to conducting himself in a disorderly manner and committing a breach of the peace.
Sheriff Allan Findlay ordered Dempsey, of Govan in Glasgow, to be of good behaviour for six months.
An earlier hearing was told Celtic were taking on Romanian outfit CFR Cluj in the UEFA Europa League tie.
Prosecutor Christopher McKnight said: “He made his way down the concourse steps.
“He entered into the Celtic dugout area and was alongside players and management.
“He attempted to obtain a photograph with Celtic manager Neil Lennon.
“Police approached him while he was heavily under the influence and he was taken into custody.”
Lawyer Gerry Devanney told the court Dempsey received a brain injury last year and his young daughter has given him a new outlook on life.
Celtic went on to win the tie 2-0 following goals by Odsonne Edouard and Mohamed Elyounoussi.
