The linesman didn't flag when the ball was struck towards the goal.
If the linesman felt at that moment the player was offside that was when he should have raised his flag.
That is his job.
The officials keep telling us they can only make decisions on what they see.
And the only thing the linesman saw was 4 or 5 irate Ross County players rushing towards him.
The lineman then believed he had made a mistake by not flagging and he believed he was correcting that mistake with his very late flag.
As the TV showed it was a very difficult decision to make, but the linesman, I believe, by not raising his flag earlier had not seen our player in an offside position, and it turned out his initial reaction was correct. Our player was not offside.
