But with the clock having ticked past the 90-minute mark, Dupraz found himself distracted and the recipient of a blow to the head from the paper plane.
What happened next though did the Toulouse boss no favours.
Instead of brushing off the blow, he seemed to unnecessarily milk the attention of his back-room staff on his team's bench, although the incident wasn't quite as bad as the time a rogue bottle wiped out half of the Barcelona team.
While their manager was distracted, the four minutes of added time saw Toulouse fail to find an equaliser as they went down to a narrow reversal.
They weren't helped, it must be said, by a red card to defender Christopher Jullien.
The result left Dupraz and his team ninth in France's top division, with 19 points from their 14 games so far this season.
Let's hope he's back fully fit for his team's next match at home to Montpellier on Wednesday evening.
