Both Steven MacLean and Frazer Wright were denied goals against Celtic on Tuesday night.
The pair both netted headers for St Johnstone against the league leaders, only for the linesman to raise his flag for offside.
MacLean's effort looked to have been correctly ruled out but Wright appears to be right to feel aggrieved, looking to be onside as the ball was whipped into the box.
St Johnstone eventually got their equaliser in the match, with Nigel Hasselbaink curling past Fraser Forster to make it 1-1.
What do you think of the decisions by the linesman? Were St Johnstone denied legitimate goals?
