Scotland internationals Alex Allan, Chris Fusaro and Huw Jones are among a further 16 players leaving Glasgow Warriors this summer.
They will be joined by Lee Jones, Niko Matawalu, Leone Nakarawa, Mesu Dolokoto, Dylan Evans, TJ Ioane, Ian Keatley, Fotu Lokotui, Robbie Nairn, Adam Nicol, D'arcy Rae, Aki Seiuli and George Thornton, who also move on.
Scotland fly-half Adam Hastings had previously agreed to join Gloucester while former Scotland back Tommy Seymour is retiring.
Centre Jones has reportedly signed for French club Bayonne, while back-row Nakawara had agreed a move to Ulster but that has collapsed after a medical report.
Glenn Bryce, Brandon Thomson and Paddy Kelly had already left Warriors.
"We'd like to thank all of our leavers for what they have done as Warriors this season,"head coach Danny Wilson told Glasgow's website.
Incoming signings already announced by Glasgow are Lewis Bean, Simon Berghan, Jamie Bhatti, Sebastian Cancelliere, Rory Darge, Jack Dempsey, Josh McKay, Ally Miller, Domingo Miotti, Sione Tuipulotu and Duncan Weir.
