Edgar steps into for injured Koch for title fight with Aldo

Despite a pair of disappointing losses to current UFC lightweight champion Benson Henderson, former titleholder Frankie Edgar (14-3-1 MMA, 9-3-1 UFC) will now get his shot at history.

USA TODAY Sports have reported a undisclosed injury has forced Erik Koch (13-1, 2-0) to withdraw from a planned UFC 153 title fight with current featherweight champion Jose Aldo (21-1, 3-0), and Edgar has agreed to step into the evening's main event.

Edgar now looks to join UFC Hall of Famer Randy Couture and Hawaiian superstar B.J. Penn as the only men to hold UFC championships in two different weight classes.

Now dubbed "UFC 153: Aldo vs. Edgar," the event takes place Oct. 13 at HSBC Arena in Rio de Janeiro. The evening's five-fight main card airs on pay-per-view.
