Gamecocks coach Steve Spurrier said Jeffery suffered some whiplash and had a sore back, but he is expected back in a couple of days.
A couple of thousand fans decked out in garnet and black lined the Bluff Road practice field across from Williams-Brice Stadium on a hot, muggy night to watch a spirited two-hour workout.
"It was a pretty nice practice," Spurrier said. "All of the coaches were really noticing the difference in our team speed. It was noticeable that our guys are faster than they've been before."
The Gamecocks have nearly all of their starters back on both sides of the ball, plus the nation's top recruit in defensive end Jadeveon Clowney.
GEORGIA TECH: The Yellow Jackets were back on the field Wednesday, giving coach Paul Johnson one more reason to stop answering questions about NCAA probation.

Johnson begins his fourth season at Georgia Tech with the program facing five years of probation.
The Yellow Jackets were without defensive lineman Denzel McCoy, who has an undisclosed medical issue that could end his career.

Floyd, who has caught more TD passes than any player in Notre Dame's storied history, said he has been to counseling, has changed his circle of friends and will stay in a residence hall instead of moving off campus.
