Celtic suffered a colossal collapse in their UEFA Champions League play-off tie against LASK Linz as the Austrian champions fought back from four goals down on aggregate to win in extra time.
Martin O'Neill's Hoops held a commanding advantage at the halfway stage after they triumphed 3-0 in the first leg at Celtic Park, and their qualification hopes were further enhanced when Callum McGregor's deflected strike found the back of the net with 21 minutes on the clock in Linz.
Celtic's appearance in the main draw of the UEFA Champions League seemed a formality until Benjamin Nygren's slack backpass offered LASK a lifeline, and the momentum soon swung against the Glasgow giants.
An emphatic start to the second half saw Robert Ljubicic reduce the deficit and with LASK scenting blood, Samuel Adeniran produced his first goal of the night with a sweeping first-time finish to pull the hosts to within one.
Celtic survived constant bombardment until the 90th minute when substitute Florian Flecker was primed to react to a Viljami Sinisalo save and prod home to force extra time - although O'Neill wasn't aware that the away goals rule is no longer in effect as he celebrated at the full-time whistle.
LASK completed their sensational comeback in the 109th minute when Adeniran delivered another pearl of a strike to condemn Celtic to the UEFA Europa League.
