As the Women's World Cup kicks off in Australia and New Zealand, up to 30 players won't be playing due to the same knee injury. Star players, including England's Beth Mead and captain Leah Williamson, are all suffering from anterior cruciate ligament (ACL) injuries that threaten their careers in the game. And women are 3.5 times more likely to suffer this type of injury compared to their male counterparts. On the Sky News Daily, Kimberley Leonard is joined by data and forensics correspondent Tom Cheshire and producer Maz Poynter who've been investigating why female players are more likely to sustain these injuries, and sports medicine specialist Dr Kate Jackson explains what teams and coaches are doing to try to prevent future injuries.
