Leicester Tigers will not be offering Argentine wing Horacio Agulla a new contract for next season because of his likely international commitments.
The 27-year-old, whose deal expires in the summer, is expected to be in Argentina's Four Nations squad.
That would mean him missing pre-season and not returning until early October.
Director of rugby Richard Cockerill told BBC Radio Leicester: "He's a bit disappointed, as we are a little bit, but you have to make tough choices."
Cockerill said Agulla's fellow countrymen could also find it difficult to win new contracts in England.
"Unfortunately for him that's the case and that may be the case for lots of the Argentine players because you will never have them for the pre-season," Cockerill added.
"They only turn up half way through the season to play for you and that will be a difficult one for lots of people."
