Why the Neeraj Chopra vs Arshad Nadeem rivalry will not happen at Silesia Diamond League

Neeraj Chopra and Arshad Nadeem have withdrawn from the Silesia Diamond League, canceling their first post-Paris Olympics rematch. Nadeem's withdrawal is due to a calf surgery, while Chopra's reason is unclear. Both athletes are now preparing for the World Athletics Championships in Tokyo, with Chopra potentially competing in the Lausanne Diamond League beforehand.
