Long and McCourt could be available but CMS outBoss John Still could select Sean Long and Paddy McCourt, who are both available for the Hatters for this weekend's game against Barnet.
Long is set to be in the Republic of Ireland Under-21s squad for their UEFA Under-21 qualifier away to Lithuania on Friday. Meanwhile McCourt is in the Northern Ireland squad to play Latvia in a friendly in Belfast on the same day.
And Still says the pair would be available for selection on the Saturday if required.
The Hatters manager, however, will definitely be without the services of injured trio Craig Mackail-Smith, Pelly Ruddock Mpanzu and Nathan Doyle.
Striker Paul Benson is likely to be involved in the squad once more after coming on as a substitute in last weekend's FA Cup win over Crawley.
