Leeds Rhinos boss Gary Hetherington blasted 6 of his rival Super League chiefs after they thwarted a move to heal the rift in the game.
The Rugby Football League has confirmed the schedule for the first week of the Super League play-offs.
Huddersfield captain Danny Brough slammed the door shut on England and will revert to representing Scotland in the World Cup.
Hull FC have parted company with head coach Peter Gentle with immediate effect.
The 47-year-old Australian had two years left on his contract but has been the subject of much speculation over his future and his exit was confirmed five days after the club's record 76-18 Super League play-off defeat by Huddersfield.
Hull owner Adam Pearson said: "The club would like to place on record their gratitude to Peter for his efforts, hard work and dedication, helping to progress the club on the field in his two seasons in charge."
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."
Huddersfield Giants fans are celebrating tonight. The team managed a 76-18 victory over Hull FC with Leroy Cudjoe starting the scoring for the Giants. It is disappointing news for Hull though. It means their season is now over.
Widnes chief executive James Rule has joined the Vikings' board of directors and become a part-owner of the Super League club. Rule, a former chief executive of Hull who joined Widnes 18 months ago, joins Steve O'Connor, Roddy Snedden, Brian O'Connor and Matt Beech as a major stakeholder.
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.
The Huddersfield Giants will go into the end of season play-offs as winners of the Super League Leaders Shield, after their 40-0 win against Wakefield clinched top spot in the table. It was their first major trophy for 51 years, and owner and Chairman Ken Davy told Calendar it's just the start.
Hull KR have signed Canterbury Bulldogs half-back Kris Keating as the successor to outgoing captain Michael Dobson.
The 24-year-old Keating will join the Robins in the autumn on a three-year contract.
He will be a straight replacement for the 27-year-old Dobson, who has secured a release in order to return to the NRL with Newcastle Knights.
– Mike Smith , Hull KR chief executive
Kris is a very good player and a nice bloke who'll bring a lot to the club, both on and off the field.
"We're delighted that we've managed to secure his signature and I'm sure our supporters will take to him pretty quickly."
Keating, a former Australian schoolboy international, started his career with Parramatta in 2008 and went on to make 41 appearances for the Eels before joining the Bulldogs ahead of the 2011 season. He was in the side that lost to Melbourne Storm in last year's Grand Final.
– Kris Keating, new Hull KR signing
It's a new challenge for me and one that I need.
"I was just plugging away at the Bulldogs when my manager told me that Hull KR were interested and I've always had a keen interest in the Super League and know quite a few of the boys who are playing over in England.
"They all have nothing but good things to say about the competition and now feels like the right time to come over and test myself in the Super League.
"I've done a fair bit of research on Hull KR and the city itself and am really excited about coming over, as is my fiancee. We just can't wait to get over there and get started."
Former Great Britain rugby league international Stuart Fielden has announced his retirement from the game with immediate effect after struggling to overcome a knee problem.
The 33-year-old former Bradford and Wigan prop, who joined Huddersfield at the start of the season, will remain at the John Smith's Stadium as part of head coach Paul Anderson's backroom team.
Fielden, who is still the game's most expensive player following his move to Wigan from Bradford for a transfer fee of around #440,000 in 2006, appeared in nine of the Giants' opening 11 matches of Super League XVIII before picking up a knee injury at Castleford in April.
The knee then became infected and Fielden has decided to hang up his boots.
Castleford Tigers have confirmed that stand off Rangi Chase has submitted a request to leave the Super League club. The 27 year old England international, who's made 24 appearances, scoring 6 tries for the club this season, won the Super League man of steel award in 2011.
He's been with the club since signing from Australian NRL side St George Illawarra in 2009.
