By winning the match, Shamrock became the Strikeforce Middleweight Champion, thereby making him the first person to win a title in all three major North American fight promotions: the UFC, WEC and Strikeforce. On January 11, 2008, it was announced that Shamrock would face Cung Le in a match on March 29, 2008, for the Strikeforce Middleweight Championship during the joint Strike force-Elite XC event at the HP Pavilion in San Jose, California. Le arguably controlled the fight, at times out-striking the more MMA-experienced Shamrock.
