Spanish assistant referee Guadalupe Porras was taken to hospital on Sunday night following a collision with a television camera during a game between Real Betis and Athletic Bilbao.
The incident, which left Porras with a bloodied face, occurred shortly after Betis had gone 1-0 up in the 13th minute.
Porras was returning to her position on the touchline when she collided with a DAZN camera.
The camera operator had been filming close-ups of the goal celebrations.
Betis medical staff rushed over to Porras to provide her with treatment before she left the stadium in an ambulance.
Porras was replaced by fourth official Holgueras Castellanos for the rest of the game, which Betis won 3-1.
Former La Liga referee Eduardo Iturralde Gonzalez told Cadena SER: "Message to [La Liga president] Javier Tebas - the camera goes where it shouldn't go.
"Please let them work, the assistant referee is as professional as a player."
