Before Brock Lesnar stepped in to the Octagon, he first signed a deal with K-1 Heros. He made is MMA debut on June 2, 2007 on the K-1 Dynamite!! USA show.
K-1 hoped to put together the largest North American MMA event in the sport’s history, as they held the event at the Los Angeles Coliseum. They succeeded, selling approximately 44,000 tickets, but that record was later broken by UFC 129.
In his mixed martial arts debut, Lesnar was scheduled to take on Hong Man Choi. However, Choi was not issued a license to fight by the California State Athletic Commission, which left K-1 Heros without an opponent for their main event.
On short notice, Korean Min Soo Kim stepped in to face Lesnar. At the time, Kim was sporting a 2-5, which made him a great opponent to introduce Lesnar to mixed martial arts.
It didn’t take long for Brock to assert his dominance against the over-matched Kim. It took Lesnar only 69 seconds to get a takedown, land a few punches that left Kim’s face a mess, and earn the TKO victory.
After his impressive debut, he was signed by the UFC. The rest is history.
