Both had been waived/injured.
Running back Akeem Hunt and offensive lineman Brandon Mosley, both waived/injured on Tuesday by the New York Giants, went unclaimed on Wednesday. Thus, the two players revert to the Giants' injured reserve list.
Both players could remain there all season and return again in 2016 to try again to make the Giants' roster. If, however, Mosley or Hunt gets healthy enough and wants to pursue an opportunity to play this season, the team and player could work out an injury settlement. That would usually be a small monetary amount, and the player would be released from IR and become a free agent able to sign with any team.
