Scotland wing Tommy Seymour admits he owes it to Max Evans to put in a winning display against England after pinching his place.
Seymour will win his sixth cap and first in the RBS 6 Nations when he runs out to face the Auld Enemy at Murrayfield on Saturday.
The Glasgow back's inclusion will come as a blow to 30-year-old Castres man Evans after he was one of the few Scots to emerge from last week's 28-6 to Ireland in Dublin with any credit.
Evans, a 38-cap international, replaced Sean Maitland midway through the first half as the New Zealand-born flyer limped off with knee and ankle injuries which have now ended his championship.
Seymour admits he was shocked to be given the nod to start against the English by head coach Scott Johnson.
"Johnno has made the call and I'm incredibly happy that I've been given my first Six Nations start," he said.
"But I thought Max played well when he came on in Dublin and if he had started I wouldn't have been surprised. He's a top quality rugby player with a huge number of caps for Scotland.
"He's a great lad as well and was the first one to come up to me and say congrats. There's definitely not any ill feeling between the two of us.
"One of the things I have thought about since Johnno told me I was starting is that I've got to go out there and do Max justice as much as anything else, because I know if he was in that shirt he would be going all out and putting in a great performance.
"I know that as long as I'm out on that park I have to do everything I can to have my team-mates' backing and their belief that the coaches made the right call."
Seymour will be one of three incoming players, along with Matt Scott and Chris Fusaro, as the injured Maitland dropped out alongside skipper Kelly Brown and centre Duncan Taylor.
