The 5 heaviest fighters in UFC history

#3 Thomas Ramirez – 410lbs

Like Matua before him, a lot of longtime fans would instantly recognise giant Puerto Rican Ramirez for being on the wrong end of one of the all-time classic UFC highlight clips. Despite weighing in at 410lbs, Ramirez was knocked out at UFC 8 by the legendary Don Frye in just eight seconds – a UFC record for the fastest knockout that stood for almost a decade before being broken – albeit unofficially – by Duane Ludwig in January 2006.

UFC 8 had a ‘David vs. Goliath’ subtitle, with an eight-man tournament all featuring big man vs. little man matches being the centrepiece. An MMA promotion would just never get away with such things today, but this was during the early days of the sport, when it could be argued that it wasn’t even a sport, more a spectacle. The other fights – Gary Goodridge vs. Paul Herrera, Paul Varelans vs. Joe Moreira and Jerry Bohlander vs. Scott Ferozzo had big size differences, but not quite like Frye vs. Ramirez.

Frye weighed in at around 205lbs – or basically half the size of his opponent. But one stiff jab from Frye and a pair of right hands later, and it was the big man who was unconscious. To make matters worse for Ramirez, he was fighting at home as a local fighter, while Frye was resoundingly booed by the fans. Not that Frye cared. He would go on to win the UFC 8 tournament and is now a UFC Hall of Famer, while Ramirez never fought in MMA again.
