The Rangers boss says a sickness bug has impacted some in the building this week, but that shouldn't impact availability for Sunday's game.
Last weekend, two goals from Ryan Naderi and a Kevin Kelsy strike earned a 3-1 victory over Neil McCann's Kilmarnock during the first game after the international break.
Rangers will host St Johnstone the following weekend before a midweek trip to Tynecastle in late October. Then a Premier Sports Cup semi-final with Aberdeen will round off the latest round of fixtures prior to the November international break.
McInnes' internationals returned unscathed from a three-week break, with Cammy Devlin the only new injury concern. The Australian international doesn't need surgery for a hamstring injury but will miss around two months of action.
McInnes offered those who had been on international duty an extra day off on Monday, but "they all came into the training centre".
