British Boxing Board of Control general secretary Robert Smith, when asked if a life ban was possible, told BBC Radio 5 Live: "Of course it is. The board have many powers - they can fine, they can suspend and they can withdraw a licence."
Chisora returned to the UK from Germany on Sunday after his astonishing altercation with Haye whom he threatened to shoot.
Chisora, who had been defeated by defending champion Vitali Klitschko in Saturday's WBC heavyweight title clash in Munich, was detained by police, along with trainer Don Charles, at Munich airport as he was preparing to board a plane home.
The pair gave statements, but were released.
German police have yet to speak to Haye after he disappeared following the unsavoury scenes.
Haye does not have a boxing licence, having officially retired in October, so the governing body is unlikely to be able to sanction him, but they will continue investigations into the event.
Smith said: "I have to speak to the chairman of the boxing federation, the police and the authorities."
