Dazien Maeda rescued a Champions League point for Celtic after Cameron Carter-Vickers' calamitous own goal against Club Brugge.
The Hoops knew a third home win would take them to the verge of the knockout stages but it was a nightmare start as Cameron Carter-Vickers inexplicably put the ball into his own net.
Brendan Rodgers' side struggled to find the brilliance they showed in their win against RB Leipzig last time out as the Belgians dominated the first half in front of a sell-out crowd.
But they did apply some pressure after the break and Maeda curled in a wonderful strike off post to pull them level with Ferran Jutgla's strike for Brugge then disallowed for offside following a VAR check.
A precious draw sees Celtic remain among the top 24 sides in the competition with three games left. Club Brugge are one point behind and also still in contention for the knockout stages.
