Daniel Imatorbhebhe, who enrolled at Florida in January and was with the Gators for spring practices, was granted a release and will enroll at USC in August, he said via text message Thursday.
He said he did not know when he would become eligible to play.
Imatorbhebhe and his family made a trip from Georgia to visit USC's campus on Wednesday and Thursday. Imatorbhebhe's younger brother, Josh, participated in the Trojans' Risings Stars camp.
Josh Imatorbhebhe, a receiver, committed to USC's 2016 recruiting class in May.
Daniel Imatorbhebhe probably will be considered a blue-shirt recruit, with his scholarship counting toward the 2016 class.
The only scholarship tight end on USC's roster is Jalen Cope-Fitzpatrick. who was academically ineligible in 2014. Coach Steve Sarkisian said last Saturday that Cope-Fitzpatrick remained ineligible, but that he was "hopeful" he would be available in the fall.
USC announced Bryce Dixon, who played in 12 games last season, was no longer enrolled in the university in May.
Oklahoma graduate-transfer Taylor McNamara is expected to join the team in training camp. His scholarship also will count toward the 2016 class.
USC relied on walk-on Connor Spears during spring practices. Walk-on Caleb Wilson, the son of defensive line coach Chris Wilson, has worked out with the team during player-run practices this month and will also be available for training camp.
