15. Pedro Rizzo vs. Andrei Arlovski
It was definitely a case of "too much too soon," but 23-year-old Andrei Arlovski proved his meddle.
The Belorussian met with the prolific Pedro Rizzo back in March of 2002, only sporting a 4-2 record at the time.
While his stature in the sport was still unproven, Arlovski showed promise early on in his career, previously TKOing future PRIDE fixture Roman Zentsov in 78 seconds and cinching the M-1 heavyweight title in the process.
Arlovski held his own against the dangerous Brazilian, who was known as one the most devastating strikers in the sport at the time. Eventually Rizzo continued to utilize low kicks to set up his hands, connecting on a devastating right hand that sent Arlovski crashing to the canvas early in the third and final round.
