Thanks for your company this evening.

We'll be back tomorrow morning for build-up and live coverage of Stranraer v Hibernian followed by the Old Firm derby which will complete the last-eight line-up.

Enjoy the rest of your Saturday.

Aberdeen manager Stephen Glass is delighted with a debut victory and quarter-final place.

"The spirit in the group was brilliant," he tells BBC Sportsound.

"We asked them at half-time to not panic. The second-half performance was unbelievable and deserved a win.

"A group that doubts itself doesn't come back against Livingston twice. We were strong minded to keep trusting what we were doing and got our rewards.

"The players can take great belief from this and there's a lot of positivity in the dressing room now."

Livingston manager David Martindale tells BBC Scotland: "I'm really happy with my players. We need to do better at their second goal, but I can't knock the boys because they gave me everything.

"We're unlucky not to be in the next round. Penalties are a lottery, so fair play to Aberdeen.

"There's more to come from us and I won't allow the season to fizzle out."

• Kilmarnock v St Mirren
• Rangers/Celtic v St Johnstone
• Stranraer/Hibernian v Motherwell

St Johnstone manager Callum Davidson tells BBC Sportsound: "All credit to Clyde, they had a real go in the last 10 to 15 minutes.

"I thought our front three played really. They adapted really well together today.

On Guy Melamed: "He links the play really well and he's a goal scorer. We're trying to keep him but we might not be able to afford to. We're working hard to try do that if we can but we might get priced out."

Livingston are upset as the final, final whistle goes just as they are winding up for a long throw-in.

This one will be settled on penalties.

Into the last minute of extra time and Livingston have a free kick. All the big men are up but the ball sails straight into the arms of goalkeeper Gary Woods.

We'll now get two more minutes of stoppage time. Will this game ever end?

The Aberdeen veteran is cautioned for a cynical trip.

Max Stryjek, the Livingston goalie, is booked for time wasting, which, of course, wastes a bit more time...
