Vince McMahon isn't keen on AJ Styles using the Styles Clash finisher, hence the reason why the Calf Crusher finish has been pushed on television. The Wrestling Observer Newsletter reports that McMahon found out about Styles breaking Yoshi Tatu's neck with the move. He decided that WWE needed to be cautious, and Styles actually stopped using the finish. The Calf Crusher then became his regular signature. However, Chris Jericho pushed for the move to be included in their PPV match, and it was allowed. It isn't outright banned, but they do want Styles to primarily be using the Calf Crusher. You can't blame WWE for their stance. Wrestler safety has to be a priority, and accidents with the Styles Clash are often down to wrestlers not taking the spot correctly. AJ can only do so much to protect his opponent. Less skilled workers may end up cracking their neck or getting a concussion if taking the bump incorrectly. In contrast, the Calf Crusher is 100% safe and easily done. Styles has had a solid start to his WWE career, supported by some decent creative and a top feud against the skilled Chris Jericho. The finishing move isn't going to make or break his career.
