Cliftonville striker Jay Donnelly has had his contract terminated by the club after being jailed for three months.
The 23-year-old was sent to prison on Tuesday for sharing an indecent image of a child.
The club had been under pressure in recent days to sack the player, reports Belfast Live.
In June 2016, Donnelly took a photograph of himself having sex with a 16-year-old girl who was wearing a Cliftonville shirt with his name and number on the back.
He shared the image with a friend and with a number of fellow players on the messaging service WhatsApp. It was later leaked on social media.
Donnelly, 23, of Ardilea Drive in Belfast, admitted the charge in November at Belfast Magistrates' Court .
He had been on bail pending the outcome of the appeal against his original sentence.
A judge hearing Donnelly's sentence appeal at Belfast County Court reduced his original jail term from four months to three on Tuesday morning.
In a statement released on their website on Thursday, the club said: "Cliftonville Football Club can confirm that Jay Donnelly has had his contract terminated with immediate effect, following the conclusion of our Disciplinary proceedings."
