Coach Nick Saban says Kelly was limited in practice Wednesday for the No. 1 Crimson Tide and likely will be again Thursday. He was hurt in Tuesday's practice.
Kelly missed three games earlier this season with a knee injury. Saban said this is "the same kind of injury he had before, but not nearly as serious."
Chad Lindsay started against Georgia State, Kentucky and Arkansas. Saban said he did "a really good job" filling in for Kelly.
Alabama has allowed just two sacks in the past 29 quarters.
