The Roar were defeated 3-2 at Queensland Sport and Athletics Centre on Tuesday night, with the club in the spotlight for having several jerseys with numbers falling off and kits patched up with sticky tape.
In a statement released on Wednesday, the club admitted to embarrassing themselves with the jerseys issues but maintained they were dedicated to improving their situation on and off the field.
"The club understands the result against Ceres-Negros FC was disappointing and the performance was unacceptable," the statement said.
"We have always worn our orange jersey with pride.
"Last night, our club disappointed many people and embarrassed ourselves with the presentation of numbering on our orange jersey. This was of no fault of BRFC kit manufacturer Umbro and we are unreservedly apologetic.
"BRFC would like to assure its members, supporters, partners and the local football community that we are fully committed to improving both on and off the field."
Brisbane went 1-0 up against their Filipino opposition through veteran striker Massimo Maccarone but the wheels fell off soon after, with Ceres scoring just before half-time and twice in the second half.
The club has a chance to make amends with an A-League clash at Central Coast on Saturday night.
