yeah i seen one once it was the first fight on a card that juan diaz was headlining apr 14, 2007

that **** was crazy the crowd was going nuts
at the end of the fight the annoucer said after seeing over thousands of fights that was the first double knockdown he had ever seen
his name escapes me this second but hes the annoucer for showtime "its showtime"
