McCalister, the Southeastern Conference's defensive player of the week last week, injured his right foot in the first quarter at South Carolina and spent much of the game in a walking boot and on crutches. McElwain said X-rays were negative, but offered no timetable for his return.
Sherit also got hurt against the Gamecocks. Ivie has missed three of the last four games.
