Carlisle defender Lubomir Michalik has been called up to the Slovakia squad for the 2012 European Championship qualifiers.
The 28-year-old featured in Slovakia's 2-1 win over Austria two weeks ago, becoming only the third player in United's history to be capped for their country while playing for the club.
Michalik will miss Carlisle's trip to either West Ham or Aldershot in the Carling Cup second round, the home league fixture against MK Dons on Saturday September 3 and the Johnstone's Paint Trophy first round clash against Accrington on Tuesday September 7 as a result of the call-up to face the Republic of Ireland and Armenia next month.
"I think we said last time, this is one of those situations where you are delighted for the player but in the back of your mind is the fact you are going to miss him for three games," Carlisle boss Greg Abbott told the club's official website.
"We have been really solid defensively over the course of the last few weeks and Lubo is a big part of that. His form earned him a call up for the Austria game, and we all saw how well he played there, so it's no surprise that they have come for him again.
"He goes with our very best wishes because it is a fantastic achievement for him."
