Craig Cathcart has been ruled out of Northern Ireland's upcoming World Cup qualifiers against San Marino and Germany.
The Watford defender has been forced out of the squad by a groin injury, prompting manager Michael O'Neill to call up veteran Aaron Hughes.
Cathcart also missed his nation's opening qualifier last month when they earned a goalless draw in the Czech Republic.
Other absences include striker Liam Boyce, who sustained a knee injury in Ross County's defeat by St Johnstone, and Wigan Athletic striker Will Grigg, out for family reasons.
Northern Ireland are at home to San Marino on Saturday before Tuesday's game against Group C favourites Germany in Hanover.
