Greig Laidlaw is ready for the responsibility of being Scotland fly-half, beginning in Sunday's RBS 6 Nations clash with Wales.

The Edinburgh captain inherits the number 10 jersey from Dan Parks, who retired on Tuesday after missing out on selection for Cardiff, in a side showing two changes from the one which lost 13-6 to England last Saturday.

He said: "I thought it (his first Test start) would be as a nine, if I'm really honest, but I'm really looking forward to the challenge of playing stand-off. It's not so much of a surprise now because I've been playing so much as a stand-off for Edinburgh and I feel as though I've been doing well."

Laidlaw has repeatedly changed half-back roles for Edinburgh this season and maintains he still wishes to be considered for both positions.

He recognises the challenge presented by the position and being the frontline goal kicker, a responsibility he has held for Edinburgh this season, and to spark Scotland's attacking play.

But Scotland are capable of defying their underdog status and profligate start to the championship against England by beating World Cup semi-finalists Wales, according to Laidlaw.

He said: "It's a big challenge. They've got great players in their side and had a great win at the weekend.

"I also believe Scotland have got great players. I think it's now time for Scotland to put in a few big performances and hopefully I can be part of that."

The only other change in the team announced on Wednesday was the inclusion of Geoff Cross, who has been named at tighthead prop in place of Euan Murray, who does not play on Sundays for religious reasons.

Uncapped Glasgow Warriors trio Weir, Stuart Hogg and Ed Kalman were also called up to the bench.
