The Blackburn midfielder suffered a hamstring issue during Saturday’s defeat at Sheffield Wednesday.
The 28-year-old came off after 68 minutes of Rovers’ 4-2 defeat to Sheffield Wednesday at the weekend and has undergone a scan on a hamstring problem at the club.
However, he will still join up with Michael O’Neill’s squad ahead of matches at home to Estonia and Belarus.
“Corry will be in later today,” O’Neill told media on Monday.
No other issues have been reported by members of the squad arriving in Belfast ahead of Thursday’s first game at Windsor Park.
