Kris Boyd was subjected to offensive, sectarian chants from Celtic fans during their clash with Dundee United at Tannadice.
Rangers hero Boyd took to the gantry for punditry as part of Sky Sports' coverage and, as usual, copped abuse.
Celtic won 3-0 thanks to strikes from Tom Rogic, David Turnbull and Liam Scales.
But Sky were forced into an apology pre-match for '"foul language" behind where the pundits were situated.
And footage has now emerged on social media showing fans direct a chant of "you're just a fat orange b*****d" towards Boyd.
Boyd responded in good humour as the legendary Ibrox goal-scorer downplayed the bigoted chants.
"I am causing them more problems right now than when I played!
"They never used to sing about me when I played against them."
