On October 16, CMLL announced Marina Shafir as Shotzi Blackheart's replacement in the October 23 Amazonas Grand Prix in Mexico City. This is a verified change in the announced tournament field, not a championship result. Independent accounts: F4W and Fightful.
Shafir joins Team International at Arena México after Shotzi withdrew following the death of her brother. Independent reporting from F4W/Wrestling Observer and Fightful identifies CMLL's October 16 announcement as the source of the substitution. The promotion's change fills a scheduled place; it does not create an extra entrant. The international side also features AEW wrestlers Queen Aminata, Megan Bayne and Harley Cameron.
What Happened
F4W describes the October 23 match as an 11-on-11 international elimination contest, with one overall winner. It has not happened yet. The report distinguishes Shotzi's family circumstances from any injury or disciplinary action.
Shafir was confirmed by CMLL in the announced international lineup on October 16. F4W and Fightful separately reported the replacement. The two accounts give the date and role of the substitution, while the earlier withdrawal story explains why Blackheart could not attend; neither source reports an already completed October 23 contest.
Why It Matters
Shafir's substitution changes the competitive makeup of Team International without changing the status of any championship. Her martial-arts background offers a different style, while Queen Aminata, Megan Bayne and Harley Cameron already provide AEW representation. Appearing in CMLL's tournament does not by itself prove a new contract, a world title challenge or a title transfer.
Accuracy matters to a site tracking championship lineages. An announced participant is not yet a tournament winner. Even a future Grand Prix winner would not automatically belong in a defended title's historical reign list. Treating this October 16 booking announcement as an October 23 match result would mislead readers about what the promotion has verified.
What Comes Next
CMLL has scheduled the Amazonas Grand Prix for Friday, October 23, at Arena México in Mexico City. Any subsequent participant changes need a separate announcement. The winner requires independently corroborated post-show results, not a preview or prediction.
For now the supported development is narrow: Shafir replaces Shotzi on Team International. This is a new October 16 booking update, separate from the earlier withdrawal announcement. No championship has changed hands, no Grand Prix winner has been crowned, and the eventual winner must remain unfilled in any result record.
