Michael Duffy’s step up the senior Northern Ireland squad has been short lived.
The Derry man has had to return to Dundee for a scan after a recurrence of a hip injury.
Having impressed in the u21’s, Duffy was named in the set up for the first time last week.
He was due to have a scan of the injury on Thursday.
Northern Ireland start their World Cup qualifying campaign away to the Czech Republic on Sunday.
