In-Game injuries: Slider “formula”
 

I think I figured out the sliders that cause in-game injuries to occurr.

Durability 30
Fatigue Rate 57

Jason Kidd had a right ankle injury (TBD) in the 4th quarter. All I did was drive the lane, and he randomly went down. His stamina was at 56.

Another instance: MyLeague. I was playing the Indiana Pacers and Victor Oladipo jammed his finger. His stamina was at 60.

These happened late in the game.

Side Note: CPU calls time outs a lot more frequently now with the fatigue rate highet, so I will continue messing around with the Stamina/Durability sliders for better results.

I know that this has been a legacy issue, but give it a try for yourself.
