International call-ups mean later return for Didz, Murph and Christophe
Didz and Murph have been named in the final Republic of Ireland squad for the games against England and Scotland this month, while Christophe is in the Scotland party.
Republic boss Martin O’Neill has cut down his squad to 27 from the 33 initially selected for the friendly against England on June 7 and the crucial 2016 European Championship qualifier against Scotland on June 13.
Both games will be played at the Aviva Stadium in Dublin, with the Republic also taking on Northern Ireland at the same venue in a behind closed doors training game this Thursday.
Daryl has been capped 14 times while Didz made his one and so far only appearance for the Irish in the 4-1 win against the United States last November.
Town return to training in the last week of June before heading to Ireland for a week of preparation work, with the first friendly of the campaign against Shelbourne on July 11.
