Completely disagree. If this had happened at any other time other than two weeks before the games and he made the same decision, would you also be saying there needs to be an investigation?
This was such a severe injury that looking at it caused him to pass out. It's not like it was a simple fracture and the time to heal would have caused him to miss the game so he strong armed someone into amputation. This was such a severe injury that amputation was a viable option, and that's what he chose.
