Cyrus Christie and David McGoldrick have been handed their first Republic of Ireland call-ups ahead of Friday's clash with Scotland.
Manager Martin O'Neill has included the uncapped duo in a 27-man squad for the trip to Glasgow on Friday and a friendly against the United States next Tuesday.
The European Championship qualifier gives Ireland the chance to maintain their unbeaten start in Group D and a victory would see them open up a six-point lead over their hosts.
Christie has impressed at right-back for Derby County this season as they have climbed to the top of the table, while striker McGoldrick has struck five times in the second tier of English football for Ipswich Town.
Stoke City defender Marc Wilson is ruled out, and also misses the friendly against the United States next week, after suffering a hamstring injury against Tottenham on Sunday.
Everton midfielder James McCarthy will be assessed prior to the Scotland encounter after he also sustained a hamstring problem against Sunderland on Sunday.
