The ankle broke when I fell after light contact, and then the hard ground actually caused my foot to fold under and cause the fractures. And now it's stronger than ever thanks to the metal plate!
The only other break (other than about 3 broken noses) that I've had due to rugby, and that was during a match, was a broken collar bone. And I didn't know for a week
That's not bad for 15 years
I do still need to convince my wife though, and now my son says he doesn't want to play (although he's not quite four so I've got a while to correct that).
