UFC lightweight champion Benson Henderson puts his title on the line later this month against the only fighter to beat him the past six and a half years. Henderson (19-2 MMA, 7-0 UFC) meets Anthony Pettis (16-2 MMA, 3-1 UFC) in the main event of UFC 164 in Pettis’ home town of Milwaukee. The fight is a rematch of the pair’s WEC finale title fight in December 2010, when Pettis took Henderson’s title to become the final WEC champ. UFC 164 takes place Aug. 31 at Bradley Center with a main card on pay-per-view following prelims on FOX Sports 1 and Facebook. Henderson was scheduled to meet T.J. Grant before Grant was forced out with an injury. And Pettis was tapped after recovering from an injury of his own that took him out of the UFC 163 main event featherweight title fight against Jose Aldo .
