Sale Sharks have released Samoan centre Andy Tuilagi from their squad in the major change for this season. The 25-year-old, known as Andy, joined in August 2008 on a four-year contract after he was released by Leeds following their Premiership relegation.
The Samoa international, who is one of six professional rugby-playing brothers, began at Leicester before his two-year stint at Leeds.
Over three seasons at Edgeley Park, Tuilagi played in 42 games and scored three tries.
Edinburgh has signed two players from the Sale Sharks in the recent transfer window. The pair become head coach Michael Bradley's first additions since the former Ireland captain took charge earlier this month.
Cox, 26, who can also operate on the flank, has represented England from schools to under-21 level and made 12 Premiership appearances last season.
Leck, 25, played five times in Europe with Sale and has turned out for England at under-16 and under-18 level.
Sale's World Cup-winning winger Ben Cohen has said that he could be retiring at the end of the season since he has been told that that he is a plus to the requirements at Sale .
The 32-year-old joined the Sharks from Brive in 2009 on a two-year contract.
"Sale don't want me anymore because they're trying to spend more money in the pack," said Cohen.
"I've got another couple of years left in me so I'll try to get a club in the Premiership. If not, I'll retire. So we'll just have to see what happens."
Ex-Sale boss Kingsley Jones will coach Russia for World Cup. The ex-Wales captain, who left Sale this month after nearly seven years, is currently in South Africa helping the Bulls build ahead of the Super 15.
Jones has been linked with rejoining ex-Sale boss Philippe Saint-Andre at Toulon and with the Dragons coach job.
"If I'm honest I fancy the opportunity of going to Toulon," Kingsley Jones said.
Sale Sharks have confirmed the departure of Kingsley Jones. Jones, who helped lead Sale to the Premiership title in 2006, has been forwards coach and head coach before taking up his current role in 2009.
He said: "I have had a very fulfilling and rewarding time at the club and it is now right to move on.
"I will be looking to get back into a role with more hands on coaching."
Andrew Sheridan has committed his future with the sale rugby union. The 31-year-old, who had been linked with a move to France this summer, joined the Sharks from Bristol in 2003 and has played 100 games for the club.
Sale chief executive Mick Hogan said: "I know he has turned down some big offers from other clubs.
"He is one of the best prop forwards in the world and we are thrilled he has made this commitment to stay with us."
Winger Mark Cueto has been given the Sale Sharks captaincy recently. England international Cueto, 31, takes over from James Gaskell, who has been sidelined for two months with an ankle ligament injury.
"The leadership skills of Mark will be vital to us," said Anglesea, who took over as coach last week following Mike Brewer's sacking.
"We are looking to Mark to lead the club forward with heart and passion."
Sale rugby union have lost Charlie Hodgson for up to one month. The 30-year-old suffered the injury during England's defeat by South Africa last month.
A statement from Sale said: "He's likely to be out of action until well into the new year."
That could make him a serious doubt for the Six Nations with England set to announce their Elite Player Squad for the competition in January.
Sale rugby union team that defeated by Exeter in a very close match. A Chris Budgen try helped the Chiefs into a 10-9 half-time lead, with Nick Macleod kicking all of Sale's points.
Exeter's Tom Johnson touched down after the restart, but Sale promptly hit back with a score from winger Rhys Crane.
A try from Andrew Higgins put Exeter two scores ahead, from where they held on despite late Sale pressure.
In bitter conditions at Sandy Park, Sale struck first with an early Macleod penalty before Davis restored parity with a place kick of his own shortly afterwards.
