Reid, who beat challenger Hassine Cherifi on a split decision in stifling conditions, was taken to Whiston Hospital.
He collapsed in his dressing room a few minutes after the bout.
The dehydrated Reid never lost consciousness but was kept until yesterday afternoon for observation. The dehydration was apparently caused by the heat generated from overhead television lights.
