Collum to take charge of Old Firm derby

Referee Willie Collum will take charge of the crucial Old Firm derby at Celtic Park on Saturday.

Collum is assisted by David McGeachie and Ross Macleod, with Don Robertson the fourth official.

Steven McLean will be the video assistant referee, assisted by Graeme Stewart.

With just three games remaining, leaders Celtic head into the final league derby of the season with a three-point cushion over Rangers.

Collum was on VAR duty for the previous derby at Celtic Park last December, a 2-1 win for Celtic.

In the controversial fallout from that game, Rangers claimed they were incorrectly denied a penalty for an Alistair Johnston handball despite Abdallah Sima being offside in the build-up.

It led to reports that Rangers had asked that Collum should not be referee the Ibrox club's matches in future, but the Scottish FA "immediately rejected" the request.
