ESPN.com confirmed the 170-pound championship fight with Bellator officials on Tuesday. The bout, which will mark Henderson's promotional debut, will headline Bellator 153 inside Mohegan Sun Arena.
Henderson (23-5) is a former UFC and WEC lightweight champion. The 32-year-old recently ended a 14-fight run with the UFC by signing a multi-fight deal with Bellator. A longtime 155-pounder, Henderson recorded back-to-back wins as a welterweight in 2015.
Fighting out of MMA Lab in Glendale, Arizona, Henderson submitted Brandon Thatch last February in a short-notice welterweight contest. After dealing with injuries last summer, he earned a split decision win against Jorge Masvidal on Nov. 28 in Seoul. He holds notable wins against Donald Cerrone, Frankie Edgar, Nate Diaz, Gilbert Melendez and Josh Thomson. He successfully defended the UFC title three times between 2012 and 2013.
Koreshkov (18-1) has not fought since he lifted the Bellator title from Douglas Lima via unanimous decision on July 17. The 25-year-old Russian is riding a five-fight win streak. He has 10 career knockouts.
Henderson has expressed interest in competing at welterweight and lightweight under the Bellator banner. The current 155-pound titleholder in Bellator is Will Brooks (17-1).
