Chael Sonnen , as expected, will be fighting Mauricio “Shogun” Rua in the UFC Fight Night 26 main event next week in Boston. Sonnen cleared his final hurdle on Thursday when the Massachusetts State Athletic Commission voted unanimously to license him for the fight. The decision came after the commission’s Medical Advisory Board reviewed Sonnen’s physical condition and medical information. Mike Roberts of MMA Inc., Sonnen’s manager, had told MMAWeekly.com after meeting with the commission earlier in the day that it appeared “likely” that Sonnen would be granted a license. Massachusetts Department of Public Safety spokesperson Terrel Harris on Thursday informed MMAWeekly.com of the commission’s approval. Unite Here, a faction of the Culinary Union, that has long been battling the UFC ’s continued expansion efforts, filed a complaint against Sonnen stemming from his January 2011 money laundering conviction
