Aberdeen manager Derek McInnes: "Over the 90-minute performance, I would say St Mirren were the better side. I thought the game was eking towards extra-time. The goal really came out of nothing.
"Joe's been outstanding for me and mistakes happen. It's just unfortunate that that's a mistake that puts us out the cup. It was more than that that was at fault and Joe's just as likely to save us and win us so many points in a season."
