Robin McBryde is ready to answer coach Mike Ruddock's call and help Wales clear the penultimate hurdle in their quest for an RBS 6 Nations Championship Grand Slam.
The Llanelli Scarlets hooker looks set to make his first Test match start since last season's RBS 6 Nations when Wales tackle Scotland at Murrayfield on Sunday.
With current first choice Mefin Davies nursing a fractured thumb and rated extremely doubtful, 35 times-capped McBryde - provided he shakes off a niggling knee problem - is on stand-by.
Ruddock plans to announce the starting line-up on Wednesday - 24 hours later than normal - as further fitness checks are conducted on Davies, McBryde, their fellow squad hooker Steve Jones, replacement scrum-half Gareth Cooper, plus backs Hal Luscombe and Rhys Williams.
McBryde is relishing the possibility of facing Scotland, complete with their highly-rated second-row combination of Scott Murray and Stuart Grimes.
"There is pressure on us, but success is going to bring you that and we are three (wins) from three, so the next game just gets bigger and bigger," said the 34-year-old, recalling Welsh victories over England, Italy and France.
"That is something we've got to live with. The more we get used to success, the more we've got to get used to this expectancy.
"In the past, when the expectancy has been there, perhaps we have been guilty of not delivering or living up to that expectancy."
Wales have only beaten Scotland once in 20 years at Murrayfield and while attention in many quarters might already be centred on a possible Grand Slam showdown with Millennium Stadium visitors Ireland next week, the Welsh players have suffered too many Edinburgh disappointments to get ahead of themselves.
"It is always a difficult place to go to," added McBryde. "The Scots tend to raise their game at home, especially in these circumstances.
"They will be aware that everybody is already talking about the Ireland game and dismissing, or overlooking, the Scottish challenge. They will be thinking that we are looking to the Ireland game as well, and they'll hope to catch us cold.
"It is all high-tempo with Scotland, and once they cross the gain-line, they keep delivering these quick rucks. If you allow them to get behind you, it is very hard to scramble around and stop them."
