The de-commitment comes after Florida landed a pledge from five-star cornerback Jalen Tabor earlier in the day, but Lammons tweet refuted the two decisions were related.
"No I Did Not Decommit Because Of Jalen Tabor('s) Commitment," Lammons tweeted. "I Decommited To Put Myself In A Better Position."
The 5-10, 170-pound U.S. Army All-American chose the Gators over South Carolina, Tennessee and Wisconsin in August, along with many others, but the Badgers and Gamecocks have been the two main schools who continued to recruit him.
"They were just showing me how everything is up there, how the dorm rooms are, how good they are from an academic standpoint, the little things like that," Lammons said at the time.
Rated the No.29 cornerback in the country by Scout.com, Lammons will take an official visit to South Carolina later this month. He's being recruited by South Carolina defensive backs coach Grady Brown.
"South Carolina is a place I want to see, and I'm very close to Grady Brown," Lammons said. "He wants me to go there, and be the best I can be."
Lammons was scheduled to take an official visit to Florida next weekend, although it's unknown if he will still take that visit.
"I will make my final decision on National Signing Day, and I will let everyone know," he said. "I'm just going to sign the papers and get ready for the next stop on this journey."
