McElwain said Monday that both plan to play elsewhere in 2016.
Dorsey, a 6-foot-2, 321-pound redshirt sophomore, is transferring to Division II Tuskegee in Alabama, McElwain said. Dorsey played in 11 games last season, mostly on special teams. He will be eligible to play immediately.
Hardin, a senior who is graduating in May, would be eligible to play elsewhere as a graduate transfer. He missed 9 of 14 field goal attempts last season. Hardin hit a game winner against Tennessee in 2014 and another one against Vanderbilt last season, but he was mostly unreliable in his three years at Florida, missing 20 of 36 attempts. Four of those were blocked.
