KSW middleweight champion Mamed Khalidov has vacated his title to set up a four-man tournament to crown a new champ. KSW officials announced the news today, saying in a press release that Khalidov (34-5-2) “does not want to hold the division up and that there is only one fight he is after at the moment.” That reference appears to be a hope for a rematch with light heavyweight champion Tomasz Narkun, whom Khalidov lost to in a superfight in March. A four-man tournament will start in October at KSW 45, the promotion announced.
