The U.S. Supreme Court delivered a historic win to the “Save Women’s Sports” movement on Tuesday, ruling 6-3 to uphold state laws that ban biological males from competing with girls and women.

The decision was met with celebration by women’s sports activists, including several high-profile Olympians.

“Today’s Supreme Court ruling is a victory for every girl who has ever dreamed of competing at the highest level,” O’Brien-Amico told Fox News Digital.

“As a three-time Olympic Gold Medalist, I am deeply grateful that I had the opportunity to compete on a level playing field with other biological females. The integrity and safety of women’s sports must be protected in every way. We can continue to find ways to honor the dignity of every person while protecting the spaces that generations of women worked so hard to build.”

“People from the far left… hopefully they wake up and just realize just how many girls are affected by this. It’s a real thing, and I think sometimes it just goes over their head and they don’t see what’s going on with the girls,” Skinner told Fox News Digital.

“Women’s sports has changed my life, providing opportunities and a career I couldn’t have got elsewhere. I get to do what I love because people fought to create and protect a space for biological women. The female category was established so biological women can compete on a level playing field,” Humphries told Fox News Digital.

“Today is a win for the generations of girls that will step on to a field, court, track, or rink. We can now all Dream Big knowing we are safe and have a fair environment to compete in any sport at all levels. It’s a big win for women’s sports in this country.”

“Today’s decision is a step in the right direction for female fairness & safety in sport! Still, it doesn’t go as far as the UK Supreme Court — it doesn’t define the meaning of ‘sex’ in law. Allowing 27 states to establish boundaries around female sport categories should give sports governance a sigh of relief; they don’t need to worry about very expensive litigation sucking their resources,” Hogshead told Fox News Digital.

“But Sport cannot have a state-by-state web of laws. Even age group and Little League athletes travel across state lines. Further, will sport governing bodies award national competitions to states like California, who do not protect females? In short, Democrats aren’t done with this issue impacting elections, power and everything else on their agenda.”

“Today the Supreme Court decision upholds the significant role biology plays in the lives of all women.  Safeguarding girls and women’s spaces is just, fair and humane,” de Varona told Fox News Digital.

“The Supreme Court made the proper decision today, allowing 27 states to continue formally protecting girls’ and women’s sports. Democratic politicians and blue states need to wake up to the biological reality of a female’s sex,” Navratilova said in a statement provided to Fox News Digital by Hogshead.

“Today’s Supreme Court ruling is inspiring because it recognizes that protecting women as a biological class is not discrimination. It affirms that fairness matters, that reality matters, and that women shouldn’t have to apologize for asking for fair and safe competition. Without Fairness, there is no sport,” Uhlaender told Fox News Digital.

“Recently, a respected academic and clinician, told me that acknowledging biological sex is discriminatory. They directed me to respected institutions like the American Psychological Association, and I was shocked to find misleading information on it. The APA suggested that the role of testosterone isn’t proven to enhance athletic performance. The causal effects of testosterone on human physiology have been understood for decades. Suggesting otherwise gives the public an inaccurate picture of the science. Things like that have made it incredibly difficult for women to advocate for fairness.”

The WBO has now officially ordered Devin Haney’s first mandatory defence of his welterweight world title.

Haney won the belt in November last year, defeating the hard-hitting Brian Norman Jr to become a three-weight world champion.

Despite a public back-and-forth with Shakur Stevenson for a catchweight bout, Haney must now face Keyshawn Davis should he want to keep his title.

After confirming that Davis was next in line recently, WBO President Gustavo Olivieri today issued the following statement:

“The WBO Championship Committee has officially ordered the commencement of negotiations for the WBO Welterweight Mandatory Championship Title Defence between World Champion Devin Haney and the WBO’s #1 world-rated contender & mandatory challenger Keyshawn Davis.

“Pursuant to the Committee’s ruling and the WBO Regulations of World Championship Contests, the parties are granted twenty (20) days to reach an agreement. Failing such agreement, purse bid proceedings may be requested, with the purse split to be distributed 75% to the Champion and 25% to the Challenger, in accordance with the WBO Rules.”

Davis is yet to fight at 147lbs, but is well-ranked due to holding the WBO belt at lightweight in the past. He only just made the super-lightweight limit for his latest fight – a unanimous decision win over Nahir Albright – and signalled shortly after that he would be moving up.

The match-up is an intriguing proposition for fans, with Davis’ speed and calculated aggression potentially a true test of Haney’s elite defence.

All eyes now turn to Haney, who may be content to drop the belt and continue in his pursuit of bigger fights against the likes of Stevenson or even a returning Gervonta Davis.
