Celtic beat Rangers on penalties to edge into the Scottish Cup semi-finals as a combustible Old Firm derby concluded in ugly scenes as fans from both sides swarmed the pitch at Ibrox.
James Tavernier and Djeidi Gassama missed from the spot after an absorbing – if poor quality – contest, allowing Tomas Cvancara the chance to seal a place in the last four after a game in which Rangers dominated.
After his penalty beat Jack Butland, Celtic fans spilled on to the field, followed by Rangers supporters, as police and stewards tried to restore order while projectiles flew through the air.
It is unclear if there were any casualties or if arrests have been made, but BBC Sport have contacted both clubs, Police Scotland, and the Scottish FA for comment.
It was an ugly end to an engrossing quarter-final.
Both sides had a goal ruled out in the 90 minutes, with Celtic’s Daizen Maeda having a header disallowed for an earlier offside before Emmanauel Fernandez saw his effort chalked off for handball in extra time.
Rangers dominated for long spells but failed to capitalise on that as Celtic held firm to earn an incredible victory, perfectly executing their four spot kicks to go through.
The headlines, however, will focus on the aftermath. It was horrible to witness and will surely bring consequences.
