A wrestler has died following a blow to neck suffered during a tag-team match with former WWE performer Rey Mysterio.
Mexican star Pedro Aguayo Ramirez, known more commonly as Hijo del Perro Aguayo, fell unconscious in the ring after supposedly receiving a flying kick from Mysterio.
The match continued for a further two minutes before the seriousness of Aguayo's injury was established by the other participants.
Aguayo, 35, was taken to a nearby hospital before being pronounced dead at 1.30am local time.
"I have no words for this terrible news," Joaquin Roldan, director of the AAA wrestling federation, posted on Twitter. "My sincerest condolences for the Aguayo Ramirez family."
An investigation has been opened by the state prosecutor's office into possible manslaughter.
