Bitter boxing rivals Nathan Cleverly and Tony Bellew had to be separated by security guards during a press conference to publicise their long-awaited rematch.
Welshman Cleverly made a successful defence of his former WBO light-heavyweight title when he defeated Bellew in 2011.
The pair will fight again but this time at cruiserweight at the Echo Arena in Liverpool on Saturday, 22 November.
The pair recently argued on BBC Radio Wales when Cleverly said he aimed to "silence" the Liverpool fighter, while Bellew said he intended to end the Welshman's career.
