Scotland will be without Richie Gray for Saturday’s meeting with Argentina after the lock was given a three-week ban for dangerous play.
An independent disciplinary committee found the 33-year-old had acted recklessly when leading with an elbow that caught the head of an opponent during Sunday’s loss to New Zealand.
The committee ruled against Gray “on the balance of probabilities”, saying there was a “high degree of danger”.
Gray will miss two games for Glasgow.
Those come at home to Leinster on 26 November and the 3 December date with Zebre in the United Rugby Championship.
“There was absolutely no malicious intention,” said Scotland assistant coach Pieter de Villiers prior to the verdict.
The committee explained Gray’s “excellent disciplinary record” had reduced the six-week entry point for such an offence by three weeks.
With Scott Cummings and Sam Skinner injured, Saracens’ uncapped Callum Hunter-Hill was called up to the squad following news of the citing.
Gray made his first Scotland start in five years against Fiji earlier this month and then continued his international renaissance by retaining his place for the 31-23 defeat to the All Blacks.
“His leadership and his experience set-piece-wise has been massive for us and his work outside set-piece as well is really good,” added de Villiers. “He has brought a lot to the table for us and it’s been great to see him in such good form.”
