The two fighters were originally scheduled to face one another at UFC 153 in Brazil, but Aldo was injured in a motorcycle accident and had to withdraw from the bout.
UFC 156 will take place on February 2nd, and the venue and ticket information will be released shortly according to the UFC website.
Edgar (14-3-1) is coming off the controversial split decision loss against Ben Henderson at UFC 150. He had previously lost to Henderson at UFC 144 via unanimous decision in which he relinquished his UFC lightweight title. Edgar has always been one of the smaller lightweights in the UFC, and many people felt that it was only natural for him to compete at 145 pounds.
Aldo (21-1) hasn’t competed since knocking out Chad Mendes at UFC 142 in January. Aldo has won 14 consecutive fights and hasn’t lost in almost seven years, but will be facing the most complete fighter he has faced since joining the Zuffa banner in 2008.
