A Spanish court could decide on Wednesday if the strike affecting the end of the La Liga season is legal.
The Spanish Football Federation (RFEF) has suspended the end of the season and the players' union (AFE) also decided to strike in a row over TV rights.
The two parties are not satisfied with a new law, supported by the Spanish league (LFP), introducing collective bargaining for domestic television rights; currently Real Madrid and Barcelona receive most of the TV money.
According to BBC Sport, a league spokesperson confirmed that the AFE and LFP have been summoned to make a court appearance on Wednesday in relation to the strike.
The proposed action has put the final two rounds of the La Liga league games in doubt, as well as the Copa del Rey final.
