Gloucester second row Tom Palmer will be spending next season in the Pro12 with Italian side Treviso.
The former England international has left Kingsholm after just one season much to the disappointment of director of rugby David Humphreys.
The 36-year-old lock won 42 caps for England between 2001 to 2012 and has played for Yorkshire Carniege, Stade Français and enjoyed two stints with Wasps.
Humphreys revealed the club were unable to keep Palmer due to salary cap constraints.
"When you look back on all the big performances this season, and every game TP has played, he has brought the commitment and work-rate of a senior international player.
"TP and Tom Savage have been two of our highest performers on a weekly basis. He has brought that and big hits every week and that's why he will be sorely missed.
"His impact off the pitch was also invaluable. He brought the playing experience he has from top environments across Europe and showed the young players how to prepare and recover from matches.
"We're very sorry to see him go. We were desperately trying to find a way to keep him but ran out of time. I'm sure he will be a great signing for Treviso and we all wish him the very best for the future."
