Celtic have suffered a major injury blow during today's Scottish Cup semi-final with Alistair Johnston limping off injured.
The Canadian full-back was later pictured in a protective boot with crutches following a 50/50 challenge with Rangers defender Borna Barisic.
Johnston received treatment from the Celtic medical team before being substituted for Anthony Ralson on 54 minutes.
TV cameras then panned to the defender in the stands where he was grimacing in pain.
