The Scottish Football Association have confirmed that they are to study video footage of Glenn Loovens’s challenge on Maurice Edu during Saturday’s Old Firm clash at Ibrox.

There was concern for the home side just before the break when Edu crumpled to the turf after apparently suffering a late tackle from the Celtic defender.

Despite initially looking like his game was over, the Ibrox midfielder was able to return to the action and help Rangers hold on to the 1-0 lead given to them by Steven Davis which took them two points clear of the champions at the top of the Premier League

An SFA spokesman said: “We review incidents every Monday morning. This incident has been drawn to our attention and will be looked at and then the referee will be asked for his opinion.

“If the referee missed the incident, and it requires further investigation, it will go to the Review Panel.”
