Lemon, a 5-foot-11, 180-pound receiver out of Los Alamitos High School in Los Alamitos, California, is the No. 22 recruit overall in the 2023 class and the No. 3 recruit in the state of California.
ESPN 300 running back Raleek Brown also decommitted from Oklahoma, only to flip to USC on Thursday. Brown is the No. 60 prospect in the 2022 cycle and became the Trojans' highest-ranked commit in that class.
Lemon's teammate, ESPN Jr. 300 quarterback Malachi Nelson, also flipped from Oklahoma to USC on Nov. 30. Nelson is the No. 3 recruit in 2023 and the No. 2 quarterback in the class behind Arch Manning.
Since Riley left Oklahoma for USC, the Sooners have had four decommitments in the 2022 class and four in the 2023 cycle.
