The 24-year-old experienced soreness in the foot in the ensuing days and scans confirmed bone stress.
With seven rounds remaining, Brisbane is hopeful Payne will be available before the end of the home and away season.
His absence is significant for Chris Fagan's team, with fellow defenders Tom Doedee and Darcy Gardiner already unavailable for the remainder of 2024 after rupturing anterior cruciate ligaments.
It leaves co-captain Harris Andrews and veteran Ryan Lester in the key defensive posts, likely to be joined by Darragh Joyce.
Brisbane travels to Perth on Friday to face West Coast at Optus Stadium on Sunday.
