Aussie Dempsey earns first Scotland start

Former Wallabies Test forward Jack Dempsey has been selected to make his first start for his adopted rugby nation Scotland as they prepare to face Argentina at Murrayfield.

The 28-year-old Glasgow flanker recently took advantage of a change in world rugby's eligibility rules to switch his allegiance from Australia to Scotland.

The former Waratahs player, who qualifies for Scotland through his late maternal grandfather, made his debut for Gregor Townsend's team as a replacement against the nation of his birth in the first autumn Test three weeks ago.

Dempsey's inclusion in the starting XV for Saturday's match, in place of the injured Hamish Watson, is one of two changes to the team that began last weekend's defeat by New Zealand.

The other tweak to the team sees Jonny Gray replacing brother Richie at lock after the latter was hit with a three-game ban for foul play against the All Blacks.

Finn Russell, who was recalled last week after his surprise omission from the initial autumn series squad, retains his place at number 10.

There are six changes to the bench, with George Turner, who missed out through injury last weekend, included among the replacements along with Jamie Bhatti, Murphy Walker, Glen Young, Andy Christie, and Cam Redpath.

Ewan Ashman, Rory Sutherland, WP Nel and Mark Bennett, who were all substitutes against New Zealand, drop out the 23-man squad.

Meanwhile, Julian Montoya returns to captain Argentina in one of four changes for the Pumas.

Montoya had been named to play against Wales last week but then withdrew with a rib injury but will be back to lead the side up against the Scots, who they narrowly defeated in July in a three-match series in Argentina.

Also in the front row, Eduardo Bello is in for Francisco Gomez Kodela while Matias Orlando replaces Matias Moroni at outside centre and Bautista Delguy takes over from Mateo Carreras on the wing.

Veteran flyhalf Nicolas Sanchez is back among the replacements for a possible first outing since tearing a calf muscle in the opening 20 minutes of Argentina's 26-18 first Test win over Scotland in July.

Australian coach Michael Cheika's side have had mixed results on their British tour -- pulling off an upset win over England at Twickenham two weeks ago but then losing 20-13 to Wales last Saturday.
