Why no injuries on my career 2k13?

Its all about what your players durability rating is its under your attributes specifically where your physical ratings are at the near bottom if your player has a low rating he will record more injuries, for instance derrick rose has a a rating of about 75-78 for his durability making him more prone to injury. My player has a rating of 99 so basically no injuries until he gets older much older hope i helped you answer your question bro good luck.
