Rugby news in brief: Williams a doubt for Six Nations openers

Wales and Ospreys wing Shane Williams has been ruled out for a minimum of ten weeks with a dislocated left shoulder.Williams suffered the injury in Saturday's 29-25 defeat to South Africa and the prognosis now makes him a serious doubt for the start of Wales' 2011 RBS Six Nations campaign. Wales' first match is at home to England on 4 February, then they travel north to face Scotland on 12 February.

Wasps back-row forward Andy Powell has also been ruled out for this weekend's match against New Zealand with a groin problem.

Allen in as cover for injured Waldouck

Leicester centre Anthony Allen has been called into the England squad ahead of Saturday's game against Samoa.The 24-year-old has been drafted in as cover for Wasps' Dominic Waldouck, who sustained a blow to the face against Bath in Sunday's LV Cup game. Allen won two caps back in 2006 when he faced New Zealand and Argentina but has not featured since.

Waldouck is being assessed by medical staff, while Wasps' Riki Flutey, who has a calf injury, is making progress in his rehabilitation. Flutey picked up the injury against Northampton on 24 October.

Ryan is cited for stamping incident

Ireland lock Donnacha Ryan has been cited for stamping in Saturday's 20-10 victory over Samoa in Dublin. Ryan, who played the last 11 minutes of the game after replacing Devin Toner, was cited by the independent citing commissioner.

His hearing will be heard by an independent Six Nations Disciplinary Committee in London today. The same committee will also hold the hearing for Samoa hooker, Ti'i Paulo, who was cited for two dangerous tackles against Connacht last week.

Moriarty did not cheat, RFU decides

Newcastle coach Paul Moriarty has been cleared of cheating over an incident in which he appeared to have fabricated an injury to prop Tim Ryan.

In last month's match against Northampton, the Falcons withdrew Kieran Brookes after a blow to the ribs. In a half-time interview, Moriarty seemed to suggest this was a temporary replacement and that Brookes would return after a rest to replace an injured player.

Ryan was duly replaced by Brookes in the second period.

RFU disciplinary officer Jeff Blackett said: "I am satisfied that there was no intention to cheat."
