IBF heavyweight champ Wladimir Klitschko gave Ray Austin some praise when asked about their March 10 bout in Mannheim, Germany. Austin did not return the favor when he spoke about the upcoming title shot with the Associated Press .
He not only vowed to knock Klitschko out, but also claims that Klitschko does not have the heart to win the fight.
"I will knock him out and return his world title belts to the United States. Klitschko has no heart," Austin said.
Austin has not lost since July of 2001, when he was stopped by Attila Levin in nine rounds.
