Moncs has been missing from recent first team and reserve squads, and Glenn Roeder explains:
"He had a crack in his ribs after a collision with Brent Rahim a month or so ago.
"We are just waiting for him to return to training, but he is well on his way to doing that."
Steve Lomas had an X-ray on his ribs after sustaining an injury against Birmingham City on Saturday, but Glenn confirms that he was given the all clear to join up with Northern Ireland this week.
"He is okay," confirms Glenn.
With his Northern Ireland colleague Grant McCann also called up to the full squad - something he puts down to joining Cheltenham on loan - Glenn confirms that he has an open mind about whether his spell will be extended in a month's time.
"I felt the move would do him good for now but we will review the situation after four weeks," he says.
Gary Breen has been called up for Eire's match with Switzerland next week, while Shaun Byrne has pulled out of the U21s through injury.
Jermain Defoe has, after all, gone with England's U21 squad for the time being, while Glen Johnson will be in action for England U19s on Thursday against Kidderminster.
Tomas Repka is still suspended for the Czech Republic but, as he announced here some weeks ago, will return to the international scene from which he had retired under the previous regime.
Meanwhile, giving his reaction to the Worthington Cup draw which pairs the Hammers with Oldham at Upton Park, Glenn says:
"It is the last thing on my mind at the moment but I was pleased, at last, to have been drawn at home."
As for West Ham's next league game, against managerless Sunderland, caretaker boss Niall Quinn says that he is sure a new appointment will be made before the fixture takes place.
Talking of caretakers, former striker Eamonn Dolan, whose twin brother is in charge of St.Patrick's in Ireland, does not expect his tenure as temporary boss of Exeter City to last long as the club have confirmed that they are looking for a boss from outside.
Eamonn is director of youth for the Grecians.
