are you sure Husband has a Wife? And if his Mum had a daughter to the same Dad, would Husband then have a Sister? Indeed if Husband was gay, could he now have a Husband under recent changes in the law?
I seems also that if 2 go into a tackle for a 50/50 ball, the one that goes in either half hearted or pulls out comes off worse.
I'm only completely guessing but I'd think that it's some damage to the medial ligament with a tear to the medial cartlidge too.
