Senior Academy member Malelili Satala will leave the club at the conclusion of the 24/25 season to join Edinburgh Rugby.
The outside back has made four senior appearances since coming through the ranks of the Tigers Academy.
On Satala, General Manager Richard Wilks said: "We wish Mali all the best in this next chapter of his rugby journey and, while disappointed to see someone of his character and ability move on, we understand his reasons for chasing this opportunity in Scotland."
