Scott and Sam were drafted in after Dougie Hall and Mike Blair were injured during Edinburgh's 25-24 Heineken Cup win over Leinster.
Scotland doctor James Robson said: "Dougie has sustained a knock to his left hip, while Mike has bruising to his left calf and right knee.
"Both are the sort of injuries you would expect from a match of yesterday's intensity."
But the initial indications are that neither player will be ruled out of the Bank of Scotland Corporate Autumn Tests at Murrayfield.
Scotland face Romania on November 11 before Pacific Islanders and Australia visit on the following two Saturdays.
Scott's promotion to the national squad means his Glasgow team-mate Fergus Thomson will join tomorrow's Scotland A training session.
And Edinburgh's Duncan Hodge and Border Reivers player Steve Jones will also train with Scotland A as Gordon Ross misses the session because of problems getting released by his club Castres Olympique.
Scotland A coach Henry Edwards said: "At this stage of the season we are reluctant to go down the route of invoking IRB regulation 9 in order to secure Gordon's release.
"If we took such an action it would also mean that Gordon would not be able to play for the next 10 days, which would be in no-one's interest.
"We've made the decision not to upset the apple cart with Gordon's club at this time as it's a long season."
But Ross will be available for the next training sessions on November 13 and 14 and for the game against Australia on November 21.
