According to Celtic FC SLO, JP Taylor, Celtic received an apology from staff at Ibrox after a Celtic physio was hit by a bottle during the recent Glasgow Derby.
The physio was hit on the back of the head needing four stitches and losing a decent amount of blood.
The Rangers have been very silent on this incident and the others on the day. Multiple missiles were thrown including a smashed bottle that delayed the second half from kicking off.

Given the dangerous nature of these incidents it would be very helpful for the Ibrox club to be vocal and condemn these actions. Instead, it’s been radio silence.
At least there has been some sort of apology.
Celtic will likely be keeping a lid on things while there’s a police investigation into these incidents.
It’s now four days after the game and no arrests have been made. It’s troubling considering it’s one of the most policed football games in the United Kingdom. Add to that the CCTV available to the club to identify culprits.
Hopefully Celtic speak out once they can.
