April 22 (Reuters) - The National ⁠Women's Soccer League and its players' union have joined Project ACL, a global initiative ⁠aimed at reducing the number of anterior cruciate ligament injuries in professional women's football.

The ‌collaboration brings the U.S.-based NWSL into a programme that was launched in England's Women's Super League two years ago in response to a call for more research into ACL tears, with women more than twice as likely to suffer the ​debilitating injury than men.
