Defender Brian Martin, who played for Berwick Rangers until January, was one of hundreds of fans who invaded the pitch after Hibs’ 3-2 win against Rangers at last year’s Scottish Cup final.
Martin, 31, was charged under the Offensive Behaviour at Football Act and pleaded guilty at Glasgow Sheriff Court.
He was fined £800 and issued with a one-year football banning order.
Martin runs an electrical business in Musselburgh, East Lothian, with his father.
He joined Berwick Rangers from Musselburgh Athletic in January 2016 after a successful career in junior football.
Martin told a daily newspaper: “I was treated fairly enough by the courts. I was just one of the unlucky ones and have got to accept it and move on. It has been a bit over the top but they have to be seen to be doing something.”
Berwick Rangers club secretary Dennis McCleary declined to comment.
