Chisora tweet cause for concern?

Dereck Chisora tweet about Daivid Haye cause for concern?

British heavyweight Dereck Chisora tweeted, "On my way to Las Vegas" Saturday, sparking speculation he was trying to track down his countryman David Haye in the aftermath of their ugly brawl in Munich a week earlier.

The brawl came in the news conference following Chisora's loss to WBC world champion Vitali Klitschko, and left him facing a lifetime ban from the sport.

Chisora threatened to "shoot [Haye] in the street" immediately after the brawl and was later arrested and released by German police without charge.

He is scheduled to appear before the British Boxing Board of Control (BBBC) for a hearing on March 14.

Haye fled the fight venue for London, claiming he feared for his life, before boarding a plane last week that was apparently headed for Vegas, The Guardian reported.

"On my way to the airport. Guess where?" Chisora tweeted Saturday afternoon, before adding about an hour later, "On my way to Las Vegas... "

Soon after, Haye tweeted an unconnected message, prompting fans to watch his interview on "That Sunday Night Show" to be aired later in the evening.

In the interview, in which Haye was speaking from Vegas, the former WBA heavyweight champion suggested Chisora needed to "check into an anger management clinic before he kills someone."

"He has problems," Haye said. "He needs to be medicated. He has issues. I hope he gets the treatment he needs.

"He said on national TV he is going to break my jaw. He said he is going to shoot me and burn me. Now he says he is going to kill me. You have got to take that seriously."

Last Saturday night's incident was sparked after Haye, who attended the Klitschko-Chisora bout as a commentator for a British outlet, began yelling at the victorious Ukrainian during the news conference, demanding a fight.

After the Klitschko camp dismissed the calls, Chisora became involved, mocking Haye for his poor performance against Klitschko's brother Wladimir last year, which cost him the WBA title.

The pair then engaged in a yelling match, with Haye branding Chisora a three-time loser, before Chisora left the stage with his microphone in hand to confront Haye face to face.

Almost as soon as a stare-down developed, Haye landed an elbow on Chisora's jaw, and the two began brawling.
