Alistair Overeem and Badr Hari will complete their trilogy and rivalry that spans 13 years. The heavyweight kickboxers will battle to headline Glory Collision 4.
Overeem and Hari are 1-1 with each other, with their first match happening back at the end of 2008 in Japan. Overeem pulled off a huge upset in their original meeting, knocking out Hari in the very first round. Their second meeting was a year later, in the 2009 K-1 World Grand Prix semi-final round, with Hari getting revenge and badly dropping Overeem twice and securing a TKO with the two knockdown rule.
