I remember aswell in his last few games at Burnley he picked up an injury right at the end of the season that most players would've probably been happy to sit out the season as a result. He played the final two games in full to try to keep them up.
For someone at that point who knew he was leaving on a free that was very serious commitment.
Of course Metatarsals and ACLs are unavoidable but I think if it's just knocks then Tarks would play through the pain barrier if required, one of those who just wants to get out and play.
