Alistair Overeem ‘s return to the octagon has been shifted from UFC 164 to the promotion’s debut event on FOX Sports 1. Mutiple sources close to the event today told MMAjunkie.com (www.mmajunkie.com) that Overeem (36-12 MMA, 1-1 UFC) is set to meet fellow standout heavyweight Travis Browne (14-1-1 MMA, 5-1-1 UFC) at UFC on FOX Sports 1 1, which takes place Aug. 17 at TD Garden in Boston.  Although the fight will be part of the night’s main card and a major attraction, it won’t even be the main event, UFC President Dana White subsequently told MMAjunkie.com. That assures at least one other significant bout will be added to the card. Overeem originally was targeted to appear at UFC 164 , which takes place Aug. 31 at Bradley Center in Milwaukee
