The crisis meant that the UEFA Champions League quarter-final had to be rescheduled to Thursday morning (AEST), while Dortmund defender Marc Bartra will require surgery after being injured by broken glass.
Despite the ordeal, away fans sitting inside the Westfalenstadion awaiting the match showed an inspirational display of solidarity as they cheered in support of their hosts and opposition.
