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.

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.
