Cardiff Blues fly-half Rhys Patchell's RBS 6 Nations hopes are over after knee surgery ruled him out for several months.
Blues rugby director Phil Davies has confirmed the 20-year-old will have an operation to correct the problem suffered in the weekend's 21-13 victory over the Dragons.
Patchell will also have shoulder surgery while he is already sidelined with the knee trouble.
And, after winning two caps on Wales' tour to Japan last summer, he will now be unable to compete for Six Nations selection.
"It is a disappointment to us to lose Patch for this period of time when he is playing so well, with many crucial games coming up in both Europe and the Pro12," boss Davies told www.cardiffblues.com.
"However, it will give others within our squad the opportunity to step up as we look to enjoy a strong start to 2014.
"We wish Rhys all the best with his rehabilitation, will give him the very best support and I know he will be determined to get back fit as soon as possible.
"We all look forward to seeing him back in a Cardiff Blues jersey in the coming months."
