Wales will be without Ken Owens for their November internationals as the Scarlets hooker requires neck surgery.
The 27-year-old, who has made 26 appearances for his country, is set to miss up to twelve weeks due to the problem he sustained in training.
“Unfortunately, Ken injured his neck in a training session a week last Tuesday,” Scarlets head of performance Andrew Walker said on Friday.
“Following thorough investigations, the scans have confirmed the he’s injured a disc in his neck.
“After a thorough process, involving consultations with three neck specialists, we have decided that surgery is the best course of action.”
Head coach Wayne Pivac added: “It’s a shame for both Ken on a personal level and the team as a whole that he will require surgery on the injury he received earlier last week to his neck.
“Ken had been playing well, but the focus now is to see him through the surgery and get him back here with us for rehabilitation.”
