Wales Coach, Steve Hansen, has confirmed that the injury will keep Parker out of the remainder of the tournament. Hansen said: "It's a blow for Sonny after his broken arm but he is going to have to do what Kevin Morgan has done so often and keep bouncing back.
"Hopefully, sooner or later he will have a run with no injuries. Other than Sonny, everyone is okay."
Tom Shanklin may be the natural replacement for Parker, he came on for the injured centre and promptly scored two tries against Ireland. Other options are moving Gareth Thomas from full back to his preferred centre role, or recalling one of the Lions duo of Dafydd James and Mark Taylor.
