Leeds quartet Ross McCormack, Tom Lees, Rudy Austin and Chris Dawson are all on international duty this week.
McCormack, who has scored three goals in his last four games for Leeds, has been called into Gordon Strachan's first Scotland squad for Wednesday night's friendly clash with Estonia at Pittodrie after being left out for most of previous coach Craig Levein's time in charge.
The 26-year-old, who has scored two goals for his country, is hoping to win his ninth cap.
Defender Lees, 21, is hoping to make his fourth appearance for Stuart Pearce's England Under-21s squad when they take on Sweden in a friendly clash at Walsall's Banks's Stadium on Tuesday night.
Austin has joined up with the Jamaica squad ahead of their next round of World Cup qualifiers in Mexico on Wednesday night and fellow midfielder Dawson, handed his first professional contract at Elland Road in October and included in Leeds' matchday squad for the recent FA Cup win over Tottenham, has been called into the Wales Under-21s squad for their friendly against Iceland in Llanelli on Wednesday.
