I understand, Turbo's strength and physical conditioning have failed him multiple times and have most likely been a massive factor in injuries such as his hamstrings, knees, and ankles. He obviously has some deficiencies in that area of his body which is letting him down. His body is not strong enough in those parts.
But injuries such as the shoulder one and the pec one he had a few years ago were when he's making a last ditch attempt at saving a try, it could've happened to any player and it was pure accident. Sport injuries aren't all just unluckiness and accidents but also aren't all just weaknesses in physical ability. Unfortunately, Turbo has suffered from both those factors with his injuries.
