Pretty sure injury insurance does not cover contracts you were never offered because of an injury. How would you actualize that?
There is a thing called "lost income insurance", but that just keeps you at or near what you currently earn.
It's called total disability insurance, and it is really popular among NCAA football players:
Leonard Fornette, for example, had a $10M insurance policy that got paid out if he didn't go in the first round due to an injury
Leonard Fournette's $10M policies and the unregulated world of player protection
All eyes will be on LSU's Leonard Fournette as he runs through college football in 2016. Should he stumble, adjusters will look for ways to run through his insurance policies.
