Wales captain Alun Wyn Jones will undergo a second shoulder operation after being injured during the Autumn Nations Series.

Ospreys lock Jones, the world's most capped rugby international with 149 Welsh caps to his name, was hurt in their 54-16 defeat against New Zealand last month.

Ospreys head coach Toby Booth said: "He has had one operation and he needs a second, so we won't really know (a detailed timescale for his recovery) until the second one is done, which is in a couple of weeks."

Wales boss Wayne Pivac has already said that he does not expect Jones to be available for Wales' Six Nations campaign, which begins against Ireland in Dublin on February 5.

Booth, though, has echoed Pivac's optimism that 36-year-old Jones will return to action before the end of this season.

"We will see where that (second operation) is and what that gives us," he added. "With all the best scans in the world, until you get in there, you don't really know.

"But he is very confident, and that's Al for you, and we will put everything around him to make his recovery as quick as possible.

"He is (confident he will play again this season). The worst thing you can say to Al is that he won't do something.

"He has got that attitude and mindset, and that's what sets him apart from a lot of other people.

"We will get him back as fast as his mind and his body allows. We are pretty confident about that."
