A summary of his contribution from the BBC text:
31' Foul By Sam Cosgrove (Aberdeen)
47' Offside, Aberdeen. Joe Lewis tries a through ball, but Sam Cosgrove is caught offside.
87' Substitution, Aberdeen, Curtis Main replaces Sam Cosgrove.
Without a doubt his contribution in the 87th minute by far and away his most effective of the whole game.
Cheers Sam
