Tyrone Clinton Spong (born 3 September 1985) is a Surinamese-Dutch professional boxer and mixed martial artist and former kickboxer.

Growing up in the Bijlmermeer neighborhood of Amsterdam, he was often involved in street fighting and began training in kickboxing at the age of thirteen, under the guidance of Lucien Carbin.

In 2004, he fought Rafi Zouheir at the Battle of Zaandam, winning his first European Muay Thai Title (World Kickboxing Network).

In December 2005, at the A-1 Combat Cup in Duisburg, Spong won his first tournament Championship after winning three consecutive fights by knockout.

In 2006, Spong had two significant victories, knockout wins over Muay Thai veteran Joerie Mes and, two weeks later, K-1 fighter Kaoklai Kaennorsing, from Thailand.

In 2007, Spong won the SLAMM world title up to 79 kg by defeating the Thai Yodchai Wor Petchpun via first-round TKO.

On 26 April 2008 Spong faced Azem Maksutaj at the K-1 World Grand Prix 2008 in Amsterdam, winning by knockout in the second round.

However, due to the referee's misleading hand signals, Corbett rushed back in and knock Spong down once more, not sure that the fight had been stopped.

He faced the legendary Dutchman Peter Aerts at an It's Showtime event in Brussels, Belgium, on 30 June 2012 and won by knockout in the third round.

As Ilunga covered up and prepared to counter, referee Mufadel Elghazaoui jumped in and stopped the fight, giving Spong the TKO win at just sixteen seconds of the first round.

[15][16][17] Although, it was later revealed that there was a "no standing eight count" rule in effect at the event as per the New York State Athletic Commission's regulations, the stoppage was still deemed premature by much of the kickboxing community.

[18][19] In a long-awaited rematch, Spong fought Corbett again at Glory 11: Chicago - Heavyweight World Championship Tournament in Hoffman Estates, Illinois, United States on 12 October 2013.

After defeating Saulo Cavalari via unanimous decision in the semifinals, he then faced Gökhan Saki in a highly anticipated rematch in the final.

Saki checked the kick, causing Spong's lower right leg to fracture immediately and end the fight via TKO.

Spong made his highly anticipated MMA debut against Travis Bartlett at World Series of Fighting 1 on 3 November 2012 in Las Vegas, Nevada, in the light heavyweight (205 lb) division.

Spong defeated Juan Carlos Salas by KO in Round 1 at Brave Warriors in Action PPV event on 27 May 2017 in Mexico.
