Castleford have released Australian scrum-half Brett Seymour from his trial period without him playing a match for the Super League club.
Castleford Tigers have drawn up a short-list of candidates for the role of head coach from nine applicants.
Castleford Tigers have announced a new signing from Leeds Rhinos.
Castleford's Australian forward Grant Millington has signed a one-year contract extension that will keep him at the club until the end of 2015.
The 27-year-old has made 44 Super League appearances since joining the Tigers from Canterbury Bulldogs two years ago.
Castleford's long-serving threequarter Kirk Dixon has signed a one-year contract extension that we will see him remain with the club until the end of 2015.
The 29-year-old goal-kicking winger or centre has amassed 992 points, including 80 tries, in 163 appearances since joining the Tigers from Hull in 2007 and said it was a "no-brainer" to extend his stay.
"It's fantastic for me and playing in front of the Tigers fans is a special thing and something that I didn't want to leave," Dixon said
Castleford coach Daryl Powell said: "I am delighted that Kirk has agreed to extend his contract with the Tigers.
"He is a pleasure to coach and works as hard, if not harder, than anyone on his individual game which makes him a role model for young players to aspire towards."
Brett Seymour has been playing first-grade rugby league for more than 13 years but he admits he will be particularly nervous when he makes his first appearance for Castleford on Sunday.
The 29-year-old Australian half-back will be playing his first match for almost 12 months when he runs out for the Tigers in their pre-season friendly against York.
He was released by Hull last April after crashing his car while suffering from depression and considered giving up the game until he was thrown a career lifeline by Castleford.
Seymour had to shed nearly 10 kilos after turning up for pre-season training grossly overweight and was forced to sit out the Tigers' Boxing Day game against Halifax but now feels ready to start to kick-start his career.
Seymour, who made his NRL debut for Brisbane Broncos at the age of 17, was hoping to put a series of off-field disciplinary issues behind him when he arrived in England two years ago.
But he slipped into a state of depression after a loss of form and almost lost his life after once more turning to drink and crashing his car.
However, friends and family rallied around and he got his life back together thanks largely to the Sporting Chance Clinic.
"I am still in touch with the people there," said the former Cronulla and New Zealand Warriors player, who has signed a 12-month contract with the Tigers.
"They have been outstanding and I wouldn't be here but for them. I usually catch up once a week to have a coffee or a chat. It is a sounding board for life and generally how things are."
Tigers coach Daryl Powell is happy to give Seymour another chance and will be hoping he can help fill the void created by the departure of Rangi Chase.
With the start of the Super League season just three weeks away, Calendar's Chris Dawkes has been to see how Castleford Tigers have been preparing:
Ireland captain Liam Finn will be back in Super League in 2014 after being snapped up by Castleford Tigers.
The 30-year-old goalkicking half-back, who had brief spells in the top flight with Halifax and Wakefield, has linked up with the Tigers following his release by neighbouring Championship club Featherstone.
Finn, who led the Irish in all three World Cup games against Fiji, England and Australia, scored 1,484 points in two spells at Featherstone, where he played under Castleford coach Daryl Powell.
– Liam Finn, new Castleford Tigers signing
I'm flattered and extremely grateful that a great traditional club like Castleford has given me the opportunity to play in Super League again.
"I didn't take my chance last time and it has been a long road back. I hope to pay that back to the club and the coaching staff with hard work and by proving to them - and to myself - that I am more than capable of being a quality Super League player for them and make the most of a second chance playing at the highest level."
– Daryl Powell, Castleford Tigers coach
Liam Finn has been a stand-out performer in the Championship for the last four seasons.
"He is an outstanding player in both half-back and hooker positions and will further enhance the quality of our competition in those positions.
"I am supremely confident he will do well in Super League as a result of his professional attitude and skill sets and I'm looking forward to working with him again here at Castleford Tigers."
Castleford have linked up with Championship One club York and will launch the partnership with a pre-season friendly on Sunday January 19.
The clubs have come together after scrapping last season's respective dual-registration agreements with Keighley and Hull.
York were relegated from the Championship in 2013 and are hoping their partnership with Castleford will help them win back their place in the second tier of professional rugby league.
Castleford prop forward Ryan Boyle has signed a two-year contract extension.
The 26-year-old, who rejoined the Tigers from Salford in mid-season, was under contract until the end of next term but has now extended his stay until the end of 2016.
Castleford Tigers have completed the permanent signing of London Broncos centre Michael Channing on a two-year deal.
The 21-year-old moved to the Tigers on loan in July and impressed enough to secure a long-term stay after scoring three tries in four Super League appearances.
Castleford coach Daryl Powell said: "Michael has fitted into the club seamlessly as both a player and a person.
"He is a young centre with a lot of potential who will continue to thrive in our culture."
Channing said: "I'm really happy to get a permanent deal sorted at Castleford. Cas are one of the big names in Super League, so it's good to be offered a contract from being on-loan."
Brett Seymour has returned to the Super League after signing a one-year deal with Castleford. The 28-year-old half-back had a high-profile exit from Hull earlier this year, with his departure from the KC Stadium preceded by two months of compassionate leave.
Seymour was taken to hospital in March after crashing his car, with his wife later saying he was "desperate", suffering from depression and may have been trying to take his own life. Hull allowed him time to deal with his off-field problems before releasing him in April.
Castleford have made Salford centre Ashley Gibson their first signing for 2014.
The 26-year-old former Leeds player, whose contract with the Reds runs out this year, is joining the Tigers on a two-year deal.
– Ashley Gibson
I'm chuffed to sign for Castleford Tigers. When my manager came to me saying that Cas were interested in me I was over the moon. There were a couple of other offers but I wanted to be playing my rugby close to home so it's a great opportunity for me in Castleford."
Ashley Gibson has spent the last four years at Salford and has scored 54 tries in 111 Super League appearances.
– Daryl Powell, Castleford coach
Ashley is a player that I have rated since I coached at Leeds when he was a young player coming through the system. He is a versatile and skilful player with a great attitude and his signing further strengthens the quality and depth in our squad for next season."
Gibson is set to face his next employers when Salford visit Castleford on Sunday in the penultimate match of the season.
