Tournament captain Alastair Kellock is not even on Scotland's bench for Sunday's Pool B clash with Argentina.
Lawson continues as skipper after leading side in win over Georgia
Scotland head coach Andy Robinson has left tournament captain Alastair Kellock out of his 22-man squad to face Argentina on Sunday.
Lock Kellock led his country to a 2-0 Test series win over the Pumas in June 2010 but did not feature in the last World Cup outing against Georgia, scrum-half Rory Lawson skippering the side instead.
The 30-year-old Glasgow Warrior has again been omitted, with Richie Gray and Jim Hamilton selected in front of him to start in the second row.
There's not even a place for Kellock on the bench - the versatile Nathan Hines has been named among the replacements as cover.
Pack alterations
Gray is one of three changes in the pack, with Geoff Cross and John Barclay also recalled in place of Euan Murray, who is unavailable due to religious reasons as the match falls on a Sunday, and Ross Rennie respectively.
In the backs, Chris Paterson starts at No.15 and Ruaridh Jackson gets the nod at fly-half, next to captain Lawson.
Scotland are seeking a sixth successive win - a feat not achieved since their 1989-90 Grand Slam-winning season.
Another triumph would also ensure they maintain their record of progressing to the knockout stages at every World Cup tournament.
Robinson said: "I have picked a team to beat Argentina - the selection is simply about this match and we must view it as another match, while affording our opponents the respect they deserve.
"We have met Argentina five times since the last Rugby World Cup so we both know each others' styles and strengths.
"Of course we can draw confidence from our victories in Tucuman and Mar del Plata last year as Argentina will retain happy memories from their win at Murrayfield in 2009.
"I also believe that Argentina - as they have demonstrated already in the last two months - are a better team than we faced on their soil last year."
