For me the angle is wrong. Bone on bone less denser bone gives.
That's why missile catching blocks are a no no.. Anyway I am not certain that this is a career end but I it isn't very unlikely. The man is 38 years old, even if he fully recovers after the operations and so on he will lose a solid year if not more from training time + possible psychological effects and the question of how useable will that leg be in the future.
Not the kind of end I would however wish for such a fighter.
