Wales flyhalf and captain Stephen Jones’ is likely to miss their Test against New Zealand on 25 November.
Jones had to be replaced 25 minutes into Wales’ match against Australia on Saturday, limping off with a knee injury which an early prognosis suggests will keep him sidelined for three weeks.
“Stephen has suffered a slight strain to the medial ligament in his knee and it’s touch and go for New Zealand,” Wales attack coach Nigel Davies told BBC Sport.
Jones’ replacement James Hook was impressive at pivot and will continue in the role for the next fortnight, which will see Wales play the Pacific Islands and Canada.
This though was little consolation for Davies who lamented the loss of Jones.
“As much as James Hook had a great game when he replaced Stephen, you have to balance that out that Stephen is our captain, he is our number one flyhalf and he is a great player,” he said.
“We have to all keep our fingers crossed that he will be ready for the All Blacks game.”
Veteran Gareth Thomas, who played his first Test in nine months in Cardiff at the weekend, is said to be the forerunner to replace Jones as captain.
