Celtic have failed to qualify from the Champions League qualifiers, losing 4-2 to Portuguese side Braga on aggregate.
First Celtic goals for Gary Hooper and Efrain Juarez proved to be the only highlights of the club's campaign after Paulo Cesar's first-half away goal killed off any slim hopes of a comeback against Sporting Braga.
Slack defending from new full-back Cha Du-Ri allowed Cesar to put Braga four ahead on aggregate midway through a disappointing first half for Neil Lennon's men.
Hooper and Juarez salvaged some pride to win the game but Celtic never built up the attacking momentum needed to prevent them dropping into the Europa League play-off round.
Elsewhere, other big-name casualties came in the form of Turkish side Fenerbahce, who lost 1-0 (3-2 on aggregate) to Young Boys after a Henri Bienvenu goal and one of last year's surprise sides Unirea Urziceni, who lost 1-0 to Russian side Zenit St Petersburg after a goalless first leg.
Ajax Amsterdam managed to hold off the challenge of PAOK Salonika to progress on away goals after a 3-3 draw. Portuguese winger Vieirinha gave the Greeks a shock lead, before two from Luis Suarez and one from Rasmus Lindgren put the Dutch side ahead. Two late goals from Dimitrios Salpigidis levelled the scores, but Ajax held on to progress.
