Harris last weekend bowled for the first time since the fifth Ashes Test in August, taking 1-42 off 12 overs for Brisbane club side Toombul.
Harris could be a late call up in the one-day tournament but is expected to be placed in cotton wool by Queensland as he follows a program set to ensure he is in peak condition for the upcoming home Ashes series.
QUICK SINGLE: Full RYOBI One-Day Cup fixture
Forrest, McDermott and Gannon were overlooked while Pomersbach will remain in Brisbane to train after opting not to play in the Twenty20 Champions League tournament due to personal matters.
The Bulls attack will be led by Ben Cutting and Matthew Gale, who have just returned from the Brisbane Heat's disappointing Champions League campaign in India, along with Luke Feldman.
The bolter was Jason Floros who played just two one-day games last season but shone in the February final against Victoria, turning the match on its head with 47 off 32 balls before Queensland snatched a two-run win.
The Bulls play six matches in 12 days in the one-day tournament, starting against Western Australia on Friday.
Queensland one-day squad: Joe Burns, Ben Cutting, Luke Feldman, Jason Floros, Matthew Gale, Chris Hartley, Nathan Hauritz, James Hopes (capt), Chris Lynn, Greg Moller, Michael Neser, Nathan Reardon, Usman Khawaja.
