Celtic have said comments made by former Rangers player Kris Boyd about Callum McGregor’s injury are “being addressed by the club”.
The Celtic captain wore a protective face mask while playing in Wednesday’s Old Firm game.
Boyd, who had two spells at the Ibrox club between 2006-2010 and 2014-2015, used his newspaper column to comment on McGregor wearing the mask.
He wrote: “Callum McGregor played with a fractured cheekbone, the fact he managed to get through the 90 minutes without anyone testing out that mask is another story, but his commitment to the team was tremendous.”
Celtic reacted to the column, which appeared in the Scottish Sun on Friday, on social media.
A statement from the club’s official Twitter account said: “With regards to comments made by former professional footballer Kris Boyd concerning Callum McGregor’s injury, we can confirm that the matter is currently being addressed by the club.”
Celtic won Wednesday’s game 3-0 to move a point ahead of their city rivals at the top of the Scottish Premiership.
