Hong Kong - Welsh great Shane Williams is likely to miss the last competitive game of his career with a hamstring injury, which has put him in doubt to play with a Barbarians side against Saracens in Hong Kong.
Team officials said the 35-year-old wing and record try scorer suffered an injury playing for the Barbarians in their 30-21 defeat to Wales in Cardiff last weekend, and was "very doubtful" for Saturday's game.
He was due to play for the BGC Asia-Pacific Barbarians, featuring legends including former All Blacks Mils Muliaina, Jerry Collins and Sitiveni Sivivatu, against English Premiership giants Saracens for the Chartis Cup.
The Asia-Pacific Barbarians also feature fellow Welsh star Martyn Williams, England No 8 Nick Easter, Samoa centre Seilala Mapusua and former Japan captain Takuro Miuchi.
"It's not good news for me because we were supposed to rotate," Muliaina said at a training session in the southern Chinese city, which is expected to be hot and humid on game day.
Williams scored a try two minutes from time to end his stellar competitive club career with a fairytale 31-30 win for Ospreys over European Cup holders Leinster last month.
The scorer of a record 58 tries in 87 Wales appearances, the 2008 IRB world player of the year ended his international career for the Barbarians in the friendly against Wales last Sunday.
