Good luck to your son on his surgery.  Sports injuries are NO FUN -- had one recently myself and 3 surgeries and a year of PT later (yeah, that was a big surprise!) -- it's still NO FUN! but much better than it was or could have been.   I was happily out shooting (hoops, that is) with my son at the park today.  I always feel for the young and strong folks it happens to -- like that Louisville basketball player!  Ouch.

If your son plays Rugby, he's got to be tough.  I'm sure he'll make it through just fine!
