Former Hull scrum-half Brett Seymour has signed a one-year deal with Castleford.
Seymour, 28, left the KC Stadium earlier this season after suffering from depression, and was released from his contract following two months of compassionate leave.
He said: “I can’t thank Steve Gill (Tigers CEO) and Daryl Powell enough for giving the opportunity to put things right.
“The way it ended at Hull wasn’t nice but I’ve got things sorted in my personal life which is the main thing.
“I’ve got to prove a point and that’s out on the paddock. I’m healthy, raring to go and ready to be back playing and I’m happy to be here at Castleford.”
Tigers Head Coach Daryl Powell said: “Brett is a quality individual who I have been really impressed with after meeting him.
“He is excited by the opportunity of playing at Castleford and his game will be ideally suited to the way we want to play next year.
“I am really looking forward to working with him next season. I know that he has a lot to prove, but that brings out the best in people and I am confident that it will in Brett.”
There were reports on Tuesday that Chase’s visa situation still hasn’t been sorted by the Red Devils.
The Kiwi-born stand-off saw a move to Hull in 2012 fall through due to complications surrounding his visa.
