British boxers David Haye and Dereck Chisora could be sent to prison for their brawl in Munich on Saturday night.
The pair clashed during the post-fight press conference following Chisora's defeat to Vitali Klitschko.
German prosecutors have told BBC Sport that Haye, whose whereabouts are currently unknown, is suspected of grievous bodily harm - a crime that carries a prison sentence of six months to 10 years.
Meanwhile, Chisora is under suspicion of malicious injury, which carries a jail sentence of up to five years.
Chisora returned to England yesterday following his arrest in Germany.
