Rugby World Cup 2015: Henry Pyrgos happy with stand-in role

Henry Pyrgos captained Scotland against Ireland

Henry Pyrgos is ready to make the most of what could be his only chance to captain Scotland at this World Cup.

Fellow scrum-half Greig Laidlaw was Scotland's man of the match in their opening Pool B win over Japan.

But Pyrgos takes over as skipper as head coach Vern Cotter rotates his squad against the USA on Sunday.

"Greig had a great game on Wednesday, but I'll focus on my role and do it to the best of my ability," said the Glasgow Warriors 26-year-old.

"I just look at it like it's a great opportunity.

"Hopefully, we get the right result."

Pyrgos led Scotland in a World Cup warm-up defeat by Ireland last month and will be determined to retain his place.

However, Laidlaw is almost certain to return for the potentially decisive meeting with South Africa in Newcastle a week on Saturday.

"I knew coming in that was how it was going to go," added Pyrgos.

"It was amazing to lead the team out against Ireland and again it's a huge honour to captain Scotland at a World Cup.

"I know how much it means to the country and I'm really excited.

"I'm not sure how I'll feel when I get out there, but it'll be a big moment for myself and my family."
