Anthony Joshua was aggressively shoved by Jarrell Miller as the feuding rivals went face to face at their first press conference in New York on Tuesday.
Joshua and Miller immediately collided before a word was spoken at Madison Square Garden, the venue which will stage their world heavyweight championship fight on June 1, live on Sky Sports Box Office.
Both men then exchanged words at close quarters, with security quickly keeping them apart, before the press conference properly begun.
