Sergey Kovalev was in no mood to engage in any more fighting talk ahead of his world title rematch with Andre Ward after storming out of their final media conference.
The Russian lost his WBA, IBF and WBO light-heavyweight titles to Ward last November and will attempt to avenge that defeat when they meet for the second time in Las Vegas on Sunday, live on Sky Sports 1 HD from 2am.
Kovalev has previously insisted he will reclaim the belts and end Ward's unbeaten record, but refused to engage in any more pre-fight talk on Thursday.
"I already said enough and I will prove it June 17. And you get prepared," Kovalev said, turning and pointing his finger directly at Ward before leaving by the back door.
Ward, sitting in his assigned seat on the podium, immediately shot back, saying: "Turn my microphone on. Don't you point your finger at me."
The American, who moved up from middleweight to face Kovalev, won a controversial first fight 114-113 on all three judges' scorecards.
