Grant Gilchrist to captain Scotland against Argentina

Grant Gilchrist will captain an inexperienced Scotland side against Argentina on Friday.
The Edinburgh lock, 23, is only one of four to retain his place in the starting XV following last Saturday's 19-17 win over Canada.
Scrum-half Grayson Hart, lock Jonny Gray and London Irish back-row Kieran Low all make their first starts.
Ross Ford will become Scotland's most-capped hooker winning his 76th cap and he is joined by Alasdair Dickinson and Geoff Cross in the front row.
Biarritz-bound Nick De Luca will form the centre partnership with Peter Horne while Duncan Weir starts at fly-half with Tom Heathcote providing cover on the bench.
“What we've seen from previous games on the tour has been a desire to play,” said head coach Vern Cotter.
“Mistakes have crept into our game because we haven't spent much time together. I've been pleased with the energy and desire to score tries but not happy with the execution.
“I'm looking to them to bring that same energy and desire to carry the ball and secure opportunities and hopefully fresh legs can help.
“I need to see what players are doing. We have to show teeth. We have to be able to attack from anywhere and we have to be able to dictate the pace and tempo of games. It's a challenge.”
David Denton was expected to be involved but had to withdraw having not recovered from a concussion.
