Graeme Morrison believes Saturday's trip to Twickenham is the perfect opportunity for Scotland to finally prove themselves to their nation.
Glasgow centre Morrison and his team-mates will travel to London to defend the Calcutta Cup knowing they must beat England to avoid a third straight season of RBS 6 Nations disappointment.
Morrison, 26, has been an ever-present in this year's Six Nations campaign, during which Scotland have lost to Wales, France and Ireland, while recording a solitary win over a poor Italy side.
Beating a resurgent England at Twickenham looks well beyond the current Scotland squad but Morrison challenged his team-mates to shake off the disappointment of Saturday's 22-15 defeat to Ireland and raise their games this weekend.
"I think that anyone in the squad who finds it difficult to get your head up to go down there and play against England probably shouldn't be there," he said.
"It's the game that everyone relishes playing in.
"We've got a lot to prove to ourselves and the nation."
Scotland played their best rugby of the championship in the first half of Saturday's match and even led at the interval.
But they were simply unable to cope with their Grand Slam-chasing opponents' fearsome forward power after the break.
"It was kind of there for the taking and we let some people down, let ourselves down, and we're hurting from that," Morrison added.
"So what better opportunity to go down and play England?"
Morrison knows Scotland must be able to maintain the first-half form they showed against Ireland if they are to stand any chance of upsetting the Auld Enemy.
"We were facing a good Irish team and we needed to go out there and do what we did in the first half for the whole game," he said.
"They were probably a bit lucky not to be further behind at half-time, but we've only got ourselves to blame in the second half."
Frank Hadden will name his team for the England game tomorrow and is hoping captain Mike Blair (back) and wing Thom Evans (shoulder) recover from injury in time.
