Even without injuries, I doubt his gameshape will get any better if you keep trying to play him so many minutes per week. But he is foul prone, looking at his stats from previous seasons. If fouls can carry over to the next game, he'd be fouling out every other game...
I don't know if you have trainees you want to play full minutes, but all I can think of to help you is:
1. set your foul trouble option to "Sit them" and
2. try decrease the pace of your offense -- less posessions, the less he has to foul.
