Respectfully disagree good sir. Smith was running for the ball and Boyle grabbed his arm. Agreed there was a grapple and Smith did put an arm over Boyle and shove him away. But this was after Boyle had grabbed his arm, as he had done about four times already in the game. It's not the most clear of images but this still image shows the first contact. Immediately prior to this Smith was running towards the ball and Boyle was running towards Smith. The still image in my opinion depicts Boyle grabbing Smiths arm, it's not the clearest image as I say, but it echoes what I saw from the stand on the day.
I will happily accept that it could have gone either way and I am extremely happy the ref allowed the game to flow in our favour.
