Callam comes in for Johnny Beattie at No. 8 after he damaged ankle ligaments in Scotland's 34-22 win over the Pacific Islanders last week. Chris Cusiter injured his shoulder in the same game and was replaced by Mike Blair at scrum half Wednesday.

Scotland beat Romania 48-6 two weeks ago in its only other November international.

``We are unbeaten at Murrayfield this year and everyone involved with the squad is proud of that,'' Scotland coach Frank Hadden said. ``We will require a top-drawer performance from our entire 22 to maintain that on Saturday.''

Rookies Rory Lawson and Alasdair Strokosch were named on the bench.
