After the episode was resolved, Portuguese referee Catarina Campos showed a white card to both medical personnel, which was received with applause and cheers from the fans at Lisbon's Estadio da Luz.
While yellow and red cards are used as a means to discipline players and coaching staff for misconduct during games, a white card can be shown in Portugal to recognise and praise acts of fair play.
The use of the white card is an initiative of Portugal's National Plan for Ethics in Sport (PNED) to influence practice sport with fair play and has been embraced by the Portuguese Football Federation (FPF) in their tournaments.
Benfica went on to win the game 5-0 to progress to the semifinals of the competition.
Saturday's derby will also be remembered because it set up a new attendance record in women's football in Portugal, with 15,032 people showing up, with the previous record back in May 2022 being 14,221.
