Jones out of Wales squad
Ryan Jones has withdrawn from the Wales squad ahead of the Six Nations because of a hamstring injury.
Jones suffered the injury in the Ospreys' Heineken Cup defeat to Leinster on Friday night. It is not yet clear if the British & Irish Lions star will miss the whole tournament - some reports suggest he has only been ruled out of Wales' first two matches.
He has been replaced in the squad by his club team-mate James King.
A Welsh Rugby Union statement read: "Wales have released Ospreys back-row Ryan Jones back to his region due to injury.
"Jones met up with the squad this morning as they began preparations for the forthcoming Six Nations and has been ruled out with a hamstring injury.
"Jones' regional team-mate James King, who made his debut for Wales last summer in Japan, has been called into the squad."
Newport Gwent Dragons hooker Sam Parry and Scarlets second-row Jake Ball will join the Wales training squad on Tuesday.
Jones, 32, has won 75 caps for his country and captained them to Grand Slam success in 2008, but has been hindered by injury this season.
His loss adds to Wales head coach Warren Gatland's concerns, with Ian Evans facing a possible ban.
The Ospreys lock was sent off for alleged stamping against Leinster and will face a disciplinary hearing.
Captain Sam Warburton has not played since the autumn defeat to Australia due to a shoulder problem, although he is expected to be fit for the tournament opener against Italy, while prop Gethin Jenkins is recovering from a leg injury.
Hooker Richard Hibbard is also nursing an injury after hurting his hip during the Ospreys loss in Dublin.
Centre Jonathan Davies is making good progress in recovering from a pectoral injury but still looks set to miss the opening two games against Italy and Ireland as Wales look to become the first side to win three outright titles in a row.
In addition to the call-up for King, who can play in the second row as well as the back row, two players will train with the squad from Tuesday in the form of Newport Gwent Dragons hooker Sam Parry and Scarlets second-row Jake Ball.
