Alun Wyn Jones will become the most capped rugby union player in test history when he leads a much-changed Wales in their Six Nations finale against Scotland in Llanelli on Saturday.

Second row forward Jones will earn a 149th cap, which includes nine for the British & Irish Lions, and move ahead of former New Zealand captain Richie McCaw on the all-time list.

“What can you say … he is a tremendous leader in this group. When he speaks everyone listens,” Wales coach Wayne Pivac said.

“He has had to wait a bit longer than we anticipated, but to do it (break the record) in a Six Nations match will be special for him.”

Just behind Jones in the scrum, loose forward Shane Lewis-Hughes will make his debut alongside Justin Tipuric and Taulupe Faletau in the back row.

“Shane is a young guy that we see having a big future in the game, though it’s probably come in a bit earlier than we anticipated with injuries,” Pivac said.

“But he’s a guy that’s trained the house down. He’s got everyone talking in camp. Alun Wyn said he’s been waiting for someone to come along like him.

“That tells you something about his work ethic and the way he trains – like a young Alun Wyn Jones.”

Wales have had a disappointing Six Nations to date with just a single victory in their four matches, but will finish above Scotland in fourth if they can get a win.
