I'm certain there is..
One of my players also had allergy for injuries and he injured several times just in something like two months.. for my luck one time was in PL and the other finished without injury..
But I'm certain there are secret personality qualities of "small bones" and "violent/physical" for players who can't keep on their hands too much time and make unclear fouls for nothing.. something like hattrick..
and of course there are more things that we don't know yet and doubt if we'll know in the future..
