Dereck Chisora sparked another pre-fight bust-up when he grappled with opponent Kubrat Pulev at their press conference.
The British heavyweight has attracted controversy in the past and lost his cool again during the head-to-head with Pulev before Saturday's European title clash in Hamburg, live on Sky Sports.
'Del Boy' slapped Vitali Klitschko at a weigh-in ahead of his 2012 points defeat and brawled with David Haye at another press conference.
This weekend's fight is an eliminator for the IBF title and the winner could be one fight away from a shot at current champion Anthony Joshua.
