Tomas Lavanini will depart Leicester Tigers at the conclusion of the 2020/21 season to join Clermont in France.
The Argentina international joined Tigers following the 2019 Rugby World Cup and has made 21 appearances for Leicester.
Speaking about Lavanini, Tigers head coach Steve Borthwick said: “We thank Tomas for his contribution to the club during the past two seasons and wish him well in his next chapter in French rugby.”
“He has been a part of the beginning of this new chapter at Tigers and we are grateful for his efforts on and off the pitch in helping us build the foundations for our future.
“We are confident in the depth we have built up in our second row and forward pack here in Leicester to take us into the future and Tomas has played a part, as a senior, experienced player in working with the young locks coming through the ranks.”
Lavanini will depart the club at the end of the current campaign.
