Scotland doctor James Robson will monitor the fitness of Simon Danielli, Dan Parks and Scott McLeod ahead of next weekend's second Test against Argentina.
The trio played the entire match in the visitors’ 21-15 defeat at Gigante de Arroyito stadium in Rosario on Saturday.
But wing Danielli and fly-half Parks suffered knee and ankle injuries, respectively, while lock McLeod picked up a knock to his thigh.
Robson is content none of the trio are badly hurt, but they have been ordered to rest until Tuesday at least.
All the players were be checked over yesterday when the squad arrive in Buenos Aires ahead of Saturday’s clash.
Their first training session is today at the GEBA club.
Chris Paterson scored all Scotland’s points on Saturday to overtake Gavin Hastings as his country’s leading scorer.
The Scots took the lead early in the second half after debutant Alvaro Tejeda's first-half try for the Pumas.
They kept their advantage until three minutes from time when Federico Todeschini scored his fourth penalty and Gonzalo Tiesi grabbed a second try to secure the victory.
Scotland coaches Andy Robinson and Sean Lineen took positives from the performance, with Argentina generally struggling to create openings.
“It was tough match, very physical. We had our momentum but couldn’t take it. Argentina are very strong at the contact,” said forwards coach Robinson.
Backs coach Lineen added: “The very few opportunities that we could create Argentina were very smart to break us down, giving the penalty chances.”
