Wales winger Shane Williams will be out of action for at least 10 weeks after dislocating his left shoulder.

Williams is now doubtful for the start of Wales's Six Nations Championship campaign in February, and has no chance of playing in either of his country's remaining Tests this month here at the Millennium Stadium, against Fiji on Friday and New Zealand a week later.

The Ospreys flyer suffered the injury just before halftime during last weekend's 29-25 loss at home to world champions South Africa.

"A scan has revealed that Shane did, as was thought, dislocate his shoulder, before it immediately moved back into place," said Wales physiotherapist Mark Davies.

"He will now undergo exploratory surgery in the next 48 hours to assess the full extent of the damage caused by the dislocation, but we know he will be out of action now for a minimum of 10 weeks."

Andy Powell has also been ruled out of the Fiji fixture with a groin problem although Wales hope to have him back in time to play the All Blacks.

"Andy will be re-assessed at the start of next week, but he won't figure on Friday night," Davies added.
