The Irish Football Association has given Grant McCann permission to join the Northern Ireland squad and complete a coaching course at a later date.
The Scunthorpe midfielder is in Belfast to take his Uefa 'A' Licence badge, but the course is not scheduled to finish until Friday.
McCann was therefore facing a problem as he was named as member of the Northern Ireland squad that is preparing to face Italy in a friendly in Pisa on Saturday.
But the 29-year-old has been granted special dispensation from the Irish FA to leave the course on Thursday and meet his international team-mates as originally planned.
With 21 caps under his belt, McCann is the third-most experienced player in the squad behind record scorer David Healy and Damien Johnson.
