London Irish have confirmed England Saxons flanker Jamie Gibson will leave the club at the end of the current campaign.
Gibson, who played for England against the Barbarians and the South African Barbarians last year, has made 69 appearances for London Irish since graduating from their academy.
However, the 22-year-old is now set to team up with Leicester Tigers next season.
"I have really enjoyed my time at London Irish," said Gibson. "I have played with some really great players and I will leave with some fantastic memories.
"The supporters have always been great to play in front of and I would like to thank them for all their support during my time with the club.
"I am moving on to a new challenge and I am looking forward to the next chapter in my rugby career."
