Tom Lockyer and Simon Sluga will be representing the Hatters on the international stage during the two-week break and could be in action for their respective nations this evening.
Defender Lockyer has travelled away with Wales and could be in-line to feature in a friendly against Finland tonight.
Him and the team will then travel to Belarus for one of two World Cup qualifiers on Sunday, and conclude their time away with a home fixture against Estonia.
Wales are currently 3rd in their group, behind a top two of Belgium and Czech Republic with hopes of being involved in next summer’s tournament.
Sluga’s Croatia have three competitive fixtures starting this evening against Russia at the Luzhniki Stadium (7:45pm kick-off).
That match is followed by a challenging away game in Slovakia on Saturday evening and three days later, they conclude the international break with a home fixture versus Slovenia.
Good luck, Tom and Simon!
