The Mexican top flight's games have been suspended for the weekend, with the match officials refusing to work after poor treatment from players.
Liga MX has suspended play for Round 10 matches after referees for the matches decided to strike.
The referee union threatened to strike earlier this week after two separate incidents of violent conduct against officials. Club America defender Pablo Aguilar made contact with referee Fernando Hernandez after America's 1-0 defeat to Tijuana on Wednesday. In the other game, ref Miguel Angel Flores sent off three Toluca players, including Enrique Triverio. The Argentine forward shoved the ref after his initial decision, earning a red card.
