Dobbie restored the home side's lead on 69 minutes only for Bryan Deasley to draw Dundee level again on 82 minutes.

Sean O'Connor fired Queen of the South in front again for the third time on 86 minutes, but their lead proved short-lived with Lyle netting his second of the contest a minute later to send the game into extra-time.
