Championship side Airdrieonians host Premiership side and current League Cup holders St Mirren for a place in the Last 8 of the Scottish Cup.

Devaney found Young on the edge of the box, who had a shot, but his effort was comfortably saved by Stone in the Airdrieonians goal.

The visitors found the breakthrough after 19 minutes. Mandron flicked the ball into the path of Devaney, who found space on the edge of the box and found the top left corner. A moment of magic from the Manchester United youngster to give St Mirren an early lead.

St Mirren continued to pile the pressure on. The ball eventually broke to Richardson inside the Airdrie box, who had a go on the volley, but his effort was well saved by Stone.

Phillips found Richardson down the right flank, who played a dangerous ball across goal looking for Mandron, but Ross came sliding in and denied the striker a tap in. From the resulting corner, Devaney sent the ball straight out of play.

On 33 minutes, the Airdrie supporters and players were adamant that their side should have been awarded a penalty. Barjonas was caught by the right leg of King, but the appeals were waved away by the referee Kevin Clancy. Mandron found space on the edge of the box down the other end, but dragged his shot past the post.

Into the second period, Henderson spotted the run of McArthur, who had a shot inside the box from a tight angle and hit the side-netting.

Not long later, Idowu found himself in acres of space inside the Airdrie box, but the substitute kicked the ground as he shot and the ball went well wide.

Strapp received a lay off from Barjonas and had a go from just outside the area, and his effort, which left George stranded, went narrowly over the top.

66 minutes in, Airdrie found the equaliser. Henderson received the ball from Barjonas, after a brilliant move, and took a touch before volleying the ball past George, to give The Diamonds a well deserved leveller. A smart finish from Henderson, who now has 17 goals this campaign.

Idowu worked the ball onto his right foot and let fly, but his effort was very well saved by Stone, who had to settle for the concession of a corner, which led to nothing.

With 2 minutes of normal time remaining, Idowu worked the ball onto his left foot and had a go, but his strike went just pass the post.

After 4 minutes of additional time, the referee blew the full time whistle, which was met with boos from the away end.

Into the opening exchanges of the second period of extra time, Calvin got on the end of Idowu’s cross, but his effort, on the stretch, went just wide.

With 5 minutes of extra time remaining, St Mirren regained the lead. Idowu got on the end of a long ball and hit the ball on the volley, which found its way past the hand of Stone.

Into additional time, McMenamin found Idowu through on goal, but the forward’s effort was saved by the foot of Stone.

St Mirren progress through to the Last 8 after a tight match against Championship side Airdrie, who made the Paisley outfit work for their win.
