Andrei Valeryevich Arlovski (Belarusian: Андрэй Валер'евіч Арлоўскі, Belarusian pronunciation: [anˈdrɛj vaˈlʲɛrɛvitʃ arˈlɔwski], Russian: Андре́й Вале́рьевич Орло́вский, born February 4, 1979) is a Belarusian kickboxer, mixed martial artist and a former Ultimate Fighting Championship heavyweight champion. He holds notable wins over Fabricio Werdum, Roy Nelson, Ben Rothwell, Tim Sylvia, and Vladimir Matyushenko.

Arlovski was born in Bobruisk and raised in Minsk, in the Byelorussian Soviet Socialist Republic of the former USSR (now Belarus). When he was younger, bullies often picked on him and beat him up. In 1994, when he was 14 years old, he finally had enough and started lifting weights to put on muscle and, he hoped, to help him deal with these bullies. Andrei only took up martial arts at the age of 16 having previously been interested in football. It was an interest in personal fitness and conditioning that led Arlovski to take an interest in combat sports.

Enrolling at the police academy in Minsk, Arlovski combined his interest in a career in law enforcement with his growing martial arts participation by taking up the required police defense course in Sambo and Brazilian Jiu-Jitsu and quickly showed himself to be a highly competent Sambo exponent. In 1999, Andrei won the European Youth Sambo Championship and the World Youth Championship. Not long after, Andrei became the first Master of Sports and then International Master of Sports. He took a silver medal at the Sambo World Cup and another silver medal at the World Sambo Championship.

Gary Goodridge (born January 17, 1966), nicknamed "Big Daddy", is a retired Canadian super heavyweight kickboxer and heavyweight mixed martial artist fighting out of Barrie, Ontario. Goodridge is known for his hard-hitting fighting style and showmanship. Prior to kickboxing and MMA, he was also one of the top ranked contenders in the world of professional arm wrestling.

Goodridge was born in Saint James, Trinidad and Tobago before moving to Barrie, Ontario, Canada. Prior to his career in combat sports, he worked as a welder at the Honda factory in Alliston, Ontario.

He was a world champion in arm wrestling, and was able to defeat the likes of greats Sharon Remez and John Brzenk in 1991 and again in 1994. He was also the super heavyweight amateur boxing champion of Canada.

In 1996, he was offered status of 4th degree black belt in kuk sool won, and a free dobak, if he would represent their school at the Ultimate Fighting Championship. He took two classes in kuk sool won before making his MMA debut in the eight-man tournament at UFC 8: David vs. Goliath in San Juan, Puerto Rico. In the quarter-finals, he faced wrestler Paul Herrera (whom Goodridge outweighed by nearly 80 lbs) and won in violent fashion by using a "goose neck", the only submission hold he had learned before the event. After Herrera attempted a fireman's carry, Goodridge trapped both of his arms in a crucifix hold and proceeded to deliver multiple elbow blows to the helpless Herrera's head, ending the bout in 13 seconds. The second elbow strike knocked Herrera unconscious, but the fight was not stopped until after Goodridge landed six more strikes. He then went on to faced Jerry Bohlander in the semis, and again won by knockout. In the finals, he took on future legend Don Frye who was trained in boxing, judo and wrestling. After Frye gained dominant position two minutes into the match, Goodridge submitted.
