@nrlphysio: Sam Walker off with a left knee injury - the same knee he suffered a partial ACL tear in last season. Unfortunately video brings concern for another ACL injury - non contact deceleration + can see some forward shift below the knee. Best hope is the instability already present in Walker’s knee allowed some shift without an actual rupture, but would be extremely lucky. Up to 40% of partial tears progress to complete ruptures - if that’s happened here obviously season over + surgery & 9 months recovery. Fingers crossed not as bad as it looks 🤞🤞 #nrl
