Northern Ireland manager Nigel Worthington led the squad in a light training session yesterday after the rigours of the victory against Poland at the weekend.
George McCartney and Steven Davis are available again following suspension. Chris Brunt is ruled out after collecting a second yellow card against the Poles.
Worthington said: "It is nice to have the points on the board. We know it is a tough group. The Czech Republic and Poland are strong teams, and Slovenia and Slovakia are no mugs. It [qualification] would be a great achievement, but we are a long way from that. We have got to go to Poland; we have to go the Czech Republic. We have got Slovenia, which is our next game, and that is where our focus is at."
Fifa is to investigate a coin-throwing incident which halted Saturday's qualifier for five minutes.
