Gavin Henson has undergone corrective surgery after dislocating a bone in his right wrist and will now be ruled out of action for a period of six to eight weeks.
The injury means Henson will miss the start of the Rugby World Cup tournament but he will remain in the care of the Wales national squad medical staff in order to ensure he returns to fitness at the earliest opportunity, in case the scenario arises in which he is called upon later in the competition.
Rhys Priestland, who also left the field during Wales' 19-9 victory over England at the Millennium Stadium yesterday, has sustained an injury to his left thigh and will be re-assessed on Monday.
Both Lee Byrne and Leigh Halfpenny have been declared fully fit and in contention for selection against Argentina in Cardiff next Saturday, in the final warm-up match of the summer before the squad leaves for RWC 2011 in New Zealand.
Stephen Jones, Ryan Jones and Gethin Jenkins, who all have calf problems, will join Priestland in reporting for injury assessment on Monday morning when further details about their progress will be established. Matthew Rees, who has a neck problem, is under continuous assessment with nothing further to report on his progress at the present time.
"Gavin underwent surgery this morning (Sunday) at the Vale hospital, to correct the dislocation to a bone in his right wrist," said national medical performance manager Prav Mathema.
"He has been given a return to play time of six to eight weeks which, whilst ruling him out of selection for the initial RWC squad, could see him available to the coaches whilst we are still in the Pool stages of the tournament.
"With that fact in mind Gavin will remain under the care of the Wales national squad medical staff in order to ensure that he returns to fitness at the earliest opportunity in case the coaches need to call him out to New Zealand for any reason.
"Both Lee Byrne (knee) and Leigh Halfpenny (ankle) have been declared fully fit and available for selection next week against the Pumas.
"Stephen Jones, Ryan Jones, Gethin Jenkins and Rhys Priestland will all be re-assessed on Monday morning when a further report on their progress will be made available."
