VIDEO: 'Invincible' Darko Milicic makes kickboxing debut, loses

In 2003, Darko Milicic was drafted ahead of Carmelo Anthony, Chris Bosh and Dwyane Wade, as well as a handful of other still-contributing NBA players. 

Milicic would average six points and 4.2 rebounds a game for six teams over the next 10 seasons, earning approximately $52 million in the process. 

It is for this reason alone that anyone is interested in Milicic's new kickboxing career. And despite losing his debut fight to Radovan Radojcic in Serbia Thursday, the former No. 2 draft pick is not short on hubris.

"The next time, it will be better," Milicic said afterwards. "I'm invincible."
