Celtic have launched an independent investigation after a crush before the Rangers game last weekend.
Five fans were injured in the incident at Celtic Park in the lead up to the Old Firm clash on Sunday 2 September.
Parkhead bosses have since apologised for the incident.
In a statement released last night, Celtic said: “Following the events prior to kick-off at the match on Sunday 2 September, the Club has instructed Fairhurst, consultants specialising in sports event safety management, to conduct an independent review to identify the contributory factors to the incident, any issues that require to be addressed and what improvements might be made to prevent a recurrence.
“The Club has requested that Fairhurst consider feedback from supporters who attended the match.
“Any supporters who attended the match and would like to provide information to Fairhurst, please do so direct to firstname.lastname@example.org .
“Any information already provided to the Club will be passed on to Fairhurst.”
