The referee has had to be substituted at half time in the Largs Thistle U19s game. 

The man in the middle required treatment midway through thr first half of an exciting cup clash between Thistle and Tass of Ardrossan. 

He appeared to be suffering from an ankle injury as play was delayed for a few minutes. 

Fortunately a man with officiating experience - Dave McPherson - was at the game and took over.

The game was goalless at full time with Tass having more opportunities although Largs had arguably the best opening and had calls for a penalty kick. 

However, Tass ran out 3-0 winners in extra time.
