Injure a player?

Was wondering if there is anyway to add an injury to a player much like 2K does in their rosters. For example, Jeff Green is no longer on the Celtics roster because of heart problems. I want to release him to the Free Agents, but I know he'll get signed immediately due to his high rating. What I want to do is add a season ending injury to him so that teams won't sign him for the first year, and then look to pick him up the next year. Thanks!

not through the game, but last year with the REDitor we could injure anyone we wanted, even hidden "injuries" like suspensions.
