South Carolina coach Frank Martin said Lawson will miss at least the next two games with a low left ankle sprain. The 6-foot-6 freshman guard hurt himself on a drive to the basket in the second half of the Gamecocks' 68-62 loss to Alabama on Tuesday.
Lawson appeared to stumble off a defender's foot and landed by the seats near the basket. He was helped up but could not put pressure on his left leg and hopped into the locker room.
Lawson, who has started all 28 games this season and is averaging 13.9 points per game, is expected to have the injury reexamined Monday.
