Burnley defender Kevin Long and West Ham midfielder Josh Cullen have been drafted into the Republic of Ireland squad for the European Qualifiers against Gibraltar and Georgia.
Long and former U21 captain Cullen, who is currently on loan at Charlton, have been called up by manager Mick McCarthy as replacements for injured duo Alan Browne and Ronan Curtis.
