Stoke City midfielder Ethan Galbraith held his hamstring as he left the field during Northern Ireland's goalless match against Georgia on Monday.
The 25-year-old, who had missed the international side's previous game against Ukraine to return home for the birth of his son, was substituted off the pitch in the 65th minute with the injury issue.
He started the match alongside Potters team-mate Justin Devenny.
Stoke return to action on Saturday when they make the trip to Bolton Wanderers (15:00 BST) in a bid to extend their five-match undefeated streak.
