Unaware that Kasper Schmeichel had moved out of his goal to offer Nicolas Kuhn a pass, Carter-Vickers passed into his own net.
The Danish keeper desperately tried to keep the ball out but was unable to prevent a calamitous own goal from Carter-Vickers.
In the aftermath, Schmeichel demanded his team-mates gather to regroup as he looked to send a message to the Celtic squad.
Callum McGregor signalled for his team-mates to join Schmeichel before kicking-off again as Joe Hart explained the meeting would be to demand Celtic return to their passing play and not be spooked and continue to struggle against Brugge.

The former Celtic keeper explained: “The message here, it is Schmeichel who called the meeting, told Callum McGregor, ‘Get everyone in here, now. I need people showing for the ball, it’s not good enough, it’s not how we play, we’re not playing how we are as a team’.
“That is the message he is giving. It will not be, ‘Get the ball down whack it and we’ll get behind it, no we play football, we show for each other, we give our team-mates options.
“Nicolas Kuhn didn’t have any options, the ripple effect was putting Carter-Vickers under pressure, Kasper Schmeichel probably trying to do too much showing for Nicolas Kuhn out of the goal.
“Carter-Vickers didn’t check, 1-0 down.”
