Stephanie Turner took a knee in protest after standing on the piste before her bout against Redmond Sullivan at the University of Maryland. She was shown a black card and informed she would not be allowed to continue in the women's foil tournament.
International Fencing Federation (FIE) rules state a fencer is not permitted to refuse to fence another properly entered fencer for any reason. USA Fencing, which enacted its transgender and non-binary policy in 2023, said: "The policy is based on the principle that everyone should have the ability to participate in sports and was based upon the research available of the day."
It added: "USA Fencing will always err on the side of inclusion, and we're committed to amending the policy as more relevant evidence-based research emerges, or as policy changes take effect in the wider Olympic and Paralympic movement."
