Celtic’s Unique Angle coverage of the 1-0 win against Dundee United has been unable to shed any light on the reason for Scott Brown’s booking.
As Albian Ajeti buries the ball into the net the Celtic skipper’s momentum carries him goalwards, as all players involved in a goal do Brown can be briefly seen shouting with Mark Connolly and two other United defenders lying close to the goal-line.
Referee Andrew Dallas appears to be looking for something, wandering towards the celebrating Celtic players with a glance towards his assistant to see if has spotted anything in the incident.
Brown is out of camera shot but there was no adverse reaction from any of the United players who seemed devastated to have held out until the 83rd minute before going behind.
No public explanations are given in Scotland to explain decisions although the fourth official will sometimes indicate to pitch-side reporters what might have happened.
