WALES coach Mike Ruddock is facing an injury crisis for the tour to Argentina and South Africa next month.

Hooker Robin McBryde has already been ruled out because he needs a shoulder operation, while scrum half Gareth Cooper and lock Robert Sidoli are also almost certainly out because of shoulder and pelvic problems, respectively.

Cooper is likely to have an operation while Sidoli has been urged to rest after being restricted heavily since the World Cup last autumn.

Now Cardiff Blues pair Iestyn Harris and Jamie Robinson have joined the list of walking wounded and are rated as doubtful as well.

Harris is suffering from a knee injury while Robinson has a back problem, both players causing concern. Robinson may also need an operation.

"We are checking the situation out today and tomorrow, but I'm very concerned about it with all the injuries," admitted Ruddock.

He has put back the announcement of the Wales squad by two days, and the 33-strong squad will now be named on Thursday.
