Kelly's injury "was" severe, but he should be ready to play again later this year. However, with unexpected surge of Sloter and with Lynch under-performed, I strongly believe the team will place Kelly in IR for the year to give him more time to fully heal, but mainly to save a roster spot so they can keep Sloter. Otherwise, Sloter will be waived at the end of preseason, and signed to the PS. With the way he performs through two preseason games, however, I doubt he will clear waiver for the PS.
