Liel Abada has made it 3-1 to Celtic as the Scottish Champions look to regain their nine point lead at the top of the Cinch Premiership.
The winger has had such an impact since replacing Maeda at half time and scored with an excellent strike. After a one-two with Aaron Mooy, the Israeli attacker fired the ball beyond Trevor Carson in the Saints nets.
Celtic have had to work hard to break down St Mirren, who were reduced to ten men in the first half when Charles Dunne was sent off.
