Johannesburg - It's gloves off when sevens rugby player Werner Kok takes on mixed martial arts fighter Garreth 'Soldierboy' McLellan in a fight for top honours on Speed Stars this week.

And if you can predict the victor you can win an advanced driving course with Opel and Michelin.

Werner Kok burst onto the international rugby stage in 2013 when he made his debut for the SA Sevens side, the Blitzbokke, at the final event of the IRB Sevens World Series in London. In just three years he and the team have won the World Games in 2013, the Commonwealth Games in 2014 and bronze at the 2016 Rio Olympics.

Kok was named World Rugby Sevens Player of the Year in 2015; not only is he devastating on attack but was also the leading tackler in the series. He is fast and fearless, attributes required to be fast on the racetrack, but which also best describe his sparring partner in this episode.

Garreth McLellan was on track for a career as a professional rugby player when a conditioning coach at the Sharks Academy introduced him to mixed martial arts. As a national champion in karate and grappling, Garreth's training made him a natural for MMA and after his professional debut in 2009 he was twice crowned EFC Africa Champion and EFC Worldwide Champion, before joining the Ultimate Fighting Championships at the end of 2014.

With a professional record of 13 victories to five losses, McLellan is looking to make it 14 wins when he meets Kok on the racetrack.
