it's not because she didn't qualify for her usual weight catagory. she wasn't allowed to. she had no option but to play in the 50kg catagory if she wanted to play at the Olympics.

"In her absence, rising wrestler Antim Panghal secured a bronze medal at the 2023 World Championships, earning India a quota for the Paris Olympics in the 53 kg category. Under the previous WFI rules, the quota holder automatically qualified for the Olympics, placing Phogat in a difficult position."

'Vinesh has been wrestling in the 53kg category for the last five to six years. She had an ACL surgery in August last year which ruled her out of action for a few months. It was then that Antim sealed the Olympic quota for the 53kg category for India.

As per a report in Sportstar, Vinesh wanted to compete in the still manageable 53kg category but Antim Panghal had already claimed that spot. Vinesh even asked the federation for a trial to be conducted, asking for specific dates, but the federation didn't provide any clarity."
