and declared a no-contest, after Overeem landed multiple knees to the groin of Cro Cop. Overeem was rumoured to be making his first title defence against Brett Rogers on 6 June at Strikeforce: Lawler vs. Shields. However, a hand injury scuttled plans for the fight. According to Golden Glory manager Bas Boon, Overeem had suffered a hand infection following a nightclub brawl early May 2009. According to Boon, Alistair and his brother Valentijn – both heavyweights – had been involved in an altercation that left five security staff needing hospital treatment and nearly cost Alistair his hand. Overeem was scheduled to make his first Strikeforce Heavyweight Championship defence in a rematch against Fabrício Werdum at Strikeforce: Carano vs. Cyborg, but had to pull out due to a hand injury, most likely caused from his nightclub brawl. Alistair defeated Tony Sylvester at Golden Glory's 10-year anniversary celebration with a standing guillotine choke. He used the same choke only eight days later to submit James Thompson at Dream 12. Overeem was set to face Andrei Arlovski at Dynamite!! 2009, but FEG instead opted to have him face Kazuyuki Fujita to keep with the DREAM vs. Sengoku theme. Overeem quickly overpowered his opponent and recorded a knockout with a knee to the head. Overeem next faced Brett Rogers on 15 May 2010 at Strikeforce: Heavy Artillery to defend his Strikeforce Heavyweight Championship. He won the fight via TKO in the first round. In his post-fight interview, Overeem declared for another time that he wants to fight Fedor Emelianenko, claiming that Fedor's management can no longer ignore his presence. The majority of Alistair Overeem's pre-fight training camp took place at the newly opened Golden Glory Gym in Pattaya, Thailand, where "The Demolition Man" concentrated on the further improvement of his Muay Thai skills. Overeem faced Todd Duffee on 31 December 2010 at Dynamite!! 2010. He defeated Duffee by way of knockout 19 seconds into the first round to win the interim DREAM Heavyweight Championship. Strikeforce Heavyweight Grand Prix In early 2011, Overeem was named as one of eight men that will take part of the Strikeforce Heavyweight Grand Prix, alongside Fabrício Werdum, Sergei Kharitonov, Brett Rogers, Josh Barnett, Andrei Arlovski, Antônio Silva and Fedor Emelianenko. A rematch with Fabrício Werdum took place on 18 June 2011, at Strikeforce: Dallas as part of an eight-man heavyweight tournament. Overeem defeated Werdum by unanimous decision (30–27, 30–27,
