The draw for the first round of the Women's Champions League in Nyon was interrupted shortly before its conclusion when one of the presenters was suddenly taken ill and had to be helped off stage.
Competitions manager Anne Vonnez swayed and momentarily stumbled backwards and was assisted by UEFA's head of women's football, Nadine Kessler, along with other officials as the live stream on the organisation's website was cut.
Defending Champions Lyon, who won a record fifth title and third in a row last season, face Norwegian side Avaldsnes.
Manchester City were paired with Atletico Madrid while Chelsea take on SFK 2000 Sarajevo.
City reached the semi-finals last season along with Chelsea. They were beaten 1-0 over two legs by Lyon, who went on to lift the trophy for a second successive season.
The Blues, meanwhile, lost 5-1 on aggregate to Wolfsburg, but Emma Hayes' side would finish the campaign by completing the FA Women's Super League and FA Cup double.
Scottish club Glasgow City, the 15th seeds, were drawn against Somatio Barcelona of Cyprus.
The round-of-32 ties will be played on September 12-13 and 26-27, with the seeded teams at home in the second leg.
