Braxton's Twitter account noted that tickets for the canceled show would be honored at a rescheduled concert date to be announced later.
Saturday marked Braxton's second hospital visit in less than three weeks due to lupus complications.
Earlier this month, the Grammy Award-winner was taken to a Los Angeles hospital for treatment.
Braxton, 49, revealed that she has lupus in 2011. The chronic autoimmune disease causes inflammation in internal organs, joints and skin.
