In early 2007, after his fight at K-1 World GP 2007 in Yokohama he was forced to have knee surgery and was not expected to return to the ring until 2008; however due to a fast recovery K-1 announced that Le Banner would participate on September 29, 2007 at the K-1 World GP 2007 in Seoul Final 16 against Russian kickboxer Ruslan Karaev. Just two days before the fight, Karaev had to pull out and was replaced by a former Korean Taekwondo practitioner, Yong Soo Park. It took Le Banner only 0'54" seconds to knock out Park in the first round with a straight punch and qualify himself for the K-1 World GP 2007 Final held on December 8, 2007 held at the Yokohama Arena, Japan.
