Liam Scales has been called into the Republic of Ireland squad after Andrew Omobamidele was ruled out of the Scotland and Armenia games with a groin injury.
The Norwich defender suffered the injury in the Canaries' 1-1 draw with West Bromwich Albion over the weekend.
The call-up is a welcome boost for Scales, who is on loan at Aberdeen from Celtic, after he was sent off for the Dons in their 3-1 defeat to Hibernian at Easter Road on Saturday.

The former Shamrock Rovers defender picked up two yellow cards inside a minute, with the second of them resulting in a Hibernian penalty which saw them draw the game level before they added two more goals in the second half.
Scales has six caps at U21 level but is yet to feature for the senior team.
A FAI statement read: "Norwich City defender Andrew Omobamidele has been ruled out of the Scotland and Armenia matches.
"The 20-year old defender sustained a groin injury in the 1-1 draw against West Bromwich Albion and has been replaced in the squad by Aberdeen defender Liam Scales.
"Scales reported for duty this morning ahead of the squad's first training session in Dublin as preparations begin for the two UEFA Nations League fixtures against Scotland and Armenia."
