Less than 24 hours after three pipe bombs exploded beside their team bus, Borussia Dortmund were required to play a football match.
The German club did not want to take the pitch for Thursday's Champions League quarter-final. One of their defenders, Marc Bartra, was sitting in hospital, having undergone surgery for a broken wrist suffered in the blasts. They lost 3-2.
But what happened before the first leg of Dortmund's tie against Monaco, what happened when the decision was made to proceed with the fixture and what happened throughout an unusually eerie 90 minutes at the Westfalenstadion, it has all been seen before in sport and will certainly be seen again.
While, generally, a team aren't always as directly affected as Dortmund, the role of sport in fraught and fractious times is, unfortunately, increasingly open to debate. A welcome distraction, a wasteful diversion, a way of showing that the bad guys' tactics are ineffective - occasions like Dortmund-Monaco can assume many hues.
It may, at first glance, seem unfair to ask athletes to perform on the pitch in the aftermath of a near-tragedy, or worse. What use chasing around a silly little ball when blood has just been spilled?
