Hull trio Ewan Dowes, Cameron Phelps and Danny Washbrook have all confirmed that they will leave the club following Sunday's Super League play-off defeat to Leeds.
Dowes and Phelps took to the social networking site Twitter following the conclusion of the 42-10 loss at Headingley to break the news.
Long-serving Dowes joined the club in 2003 from Leeds and made over 200 appearances for the Black and Whites.
"That was officially my last game for Hull fc last night," said 30-year-old Dowes.
"It's been an awesome nine years, gutted to be leaving. Gonna miss the lads and fans."
Phelps spent just six-months at KC Stadium after joining as a replacement for Jordan Tansey following the full-back's early-season sacking.
"Thanks for the year found out Wednesday via letter that I wasn't to be re-signed. Enjoyed hull. Wish I could stay," he said on the social networking site.
The club have also confirmed that Tongan forward Epalahame Lauaki will depart.
