For the record, an injury suffered in college does indeed qualify for the NFI list. As long as it's not NFL related. And even if the team pays the player, it's exempt from the cap. Unless he was moved from the NFI to pup, he can be put on NFI. Just can't return to NFI in the same league year. It's also a very common move to place an injured player who is drafted onto the NFI list. Especially when they are not expected to play the entire season. The salary issue are usually agreed upon during contract discussions prior to signing.
