The centre was sin-binned for rushing out of the line and crunching Kalyn Ponga in the second half of the Blues' game-two capitulation at the MCG on Wednesday.
Queensland scored two tries in his absence and cruised to a 44-24 win that sends the series to a decider at Suncorp Stadium on July 8.
Brisbane's Staggs will be available after being handed a grade-two careless high tackle charge that carries a fine equivalent to 13 per cent of his match fee.
The penalty shakes out to $3900, with changes to the judiciary code in 2022 meaning players are increasingly able to dodge NRL suspensions for illegal tackles committed in Origin.
Blues forward Victor Radley can accept a fine, seven per cent of his match fee, for his first-half shot on Trent Loiero.
While it is now confirmed he will be available, Staggs appears far from  certain to retain his spot at right centre for Origin III after a tough performance in the loss.
Staggs scored the opening try, but was monstered by opposite man Hamiso Tabuai-Fidow thereafter and came up with three errors.
He was far from alone, with new halves pairing Nathan Cleary and Mitch Moses among others who struggled to perform at their elite best.
Blues coach Laurie Daley appeared reluctant to rush into any in-game selection decisions, when NSW leaked 36 second-half points.
But Origin legend Cameron Smith recommended "four or five changes" in commentary for the Nine Network after fulltime, and the Blues have a wealth of centre options.
South Sydney's Latrell Mitchell has an excellent history at Origin level and is likely to have recovered from a back issue in time.
But he has not played since round nine and will have a maximum of one game under his belt before game-three teams are selected.
Stephen Crichton (shoulder) and Casey McLean (quad) were both scratched from the game-two squad amid injury concerns, but the former at least looks set to be fit.
