Cardiff - Wales have been dealt a blow in the build-up to their title-deciding Six Nations clash with England, after assistant coach Robin McBryde confirmed on Tuesday that captain Ryan Jones will miss the match through injury.
Jones, who has captained his country a record 32 times, hurt his shoulder in the weekend win over Scotland at Murrayfield and had to go off in the second half.
"Ryan is not going to be available. He has broken a bone in his shoulder and he is now under the management of the Ospreys," said McBryde. "It looks as though he will be out for six to eight weeks."
Sam Warburton, who led Wales to the Grand Slam last year, is expected to regain leadership duties against England at the Millennium Stadium in Cardiff on Saturday.
Justin Tipuric is expected to be called up to play at openside flanker, with Warburton wearing the number six shirt.
England are bidding to win their first Grand Slam since 2003 but Wales can pip them to the Six Nations title if they win by eight points or more.
