At what point can you sub in an injured player?

I was going through the injury report for each team and was surprised by 2 things

Peyton with broken ribs is a 91..only 4 points decreased

and LaVar Arrington is 87 with a broken forearm

I was in shock, then poor Terrell Davis had a torn ACL and was a 0

What is really cool is that the types of injuries are reflected in the ratings as well. If a WR has a broken hand, his catch rating will go way down but things like speed aren't affected. Very realistic.

Amos got hurt he had a hip pointer and his rating went down to a 6...His speed was a 13
