According to UFC president Dana White, who released the information to USA Today, UFC featherweight champion Jose Aldo will next step into the cage with Anthony Pettis, who is dropping down to 145 pounds. The fight will take place on August 3 at a location yet to be determined and will serve as the main event of whatever card it is placed on. Aldo vs. Pettis should be an absolute barnburner of a fight, so you can expect this to be one of the most anticipated bouts of 2013. Baker Fills In For Weedman An injury to Brent Weedman has forced him out of the Bellator Season 8 Welterweight Tournament and in his place steps Bryan Baker, who will fight Douglas Lima at Bellator 90, Bellator officials today said. It’s an unfortunate turn of events for Weedman, who defeated Marius Zaromskis in the opening bout of the welterweight quarterfinals, but Bellator’s tournament format — wherein a fighter must fight three times in three months in order to win — means an injury can be lethal. Mulhern Replaces Pierson, Meets Story at UFC 158 An injury to Sean Pierson had opened up the door for former UFC fighter Quinn Mulhern to make his UFC debut. According to Mulhern on Twitter today, he’ll be taking on Rick Story at UFC 158, which takes place March 16 in Montreal, Quebec, Canada. Mulhern is the latest Strikeforce fighter to cross over to the UFC, and after seeing his fellow Strikeforce alum go 3-0 at UFC 156, there’s no doubt he’ll be motivated to pick up a big win over Story, who needs a W desperately himself.
