The Kilmarnock striker was in the squad for their Scottish Premiership clash with St Mirren, but failed to get off the bench.
So he would have been aware of the score between his old team and their fierce rivals at Ibrox.
Boyd wasn’t in the Sky Sports studio for their coverage of the game due to his own duties at Killie, but he’s saved his opinion for today.
And he’s used his Instagram account to poke some fun at Celtic fans for the 1-0 defeat:
Boyd is never shy in giving his opinion and often angers Celtic fans with controversial views on their team.
His claim that there was a split in the dressing room earlier in the season led to one supporter poking fun at him about it while he sat on the bench during the Hoops’ 5-1 thrashing of Killie last month.
We shouldn’t be surprised Boyd has decided to post this today.
