Yes I have checked out a real injuries list... I actually have a post on a Real injuries vs Madden injuries thread.
My QB got injured twice in that game. The last one, I was two feet out of bounds and the cpu started the tackle animation.
I usually play with injuries at 10-15, but I played this game at 28 because I tried some new sliders.
Madden has the volume of injuries pretty close to correct, but the injuries are much more severe. After the game, I checked the Injury Report and two players on other teams have broken vertebrae and there are 5-6 players out for at least 30-35 weeks.
