Authorities in the central state of Aguascalientes say the incident began when the suspects made catcalls at a young woman outside a bar in the state capital of the same name.
The 22-year-old victim defended her, and the players allegedly got out of their car and punched and kicked him.
They were later detained, and the victim was hospitalized.
Necaxa issued a statement repudiating violence on and off the field. The club said it was awaiting results of the investigation.
The state prosecutor’s office said Gorocito and Molina were jailed Monday.
