The scrum is definitely not good, and is the main source of degenerative spinal injuries. The bulk of other injuries are muscular (sprains, pulls) and bruises.

The scrum is definitely not good, and is the main source of degenerative spinal injuries. The bulk of other injuries are muscular (sprains, pulls) and bruises. The rules of the game enforce a direction of play that makes head on attacks far less (maybe even none) likely than American football. But it's still a brutal sport with lasting repetitive use injuries - they just don't tend to be head injuries as much.
