Just a few weeks before the event takes place, and UFC officials have been forced to re-work UFC 169.
An injury to Kyoji Horiguchi has knocked him out of a planned prelim encounter with Chris Cariaso. According to UFC officials, Danny Martinez will step in his place.
The card features a pair of world championship matches, as Renan Barao defends the UFC bantamweight title against Urijah Faber, and Jose Aldo puts his UFC featherweight gold on the line vs. Ricardo Lamas.
Horiguchi (12-1) was victorious in his Octagon debut over Dustin Pague last year, and was planning a move to flyweight after competing in the bantamweight division.
Cariaso (15-5) also moved down to flyweight last year, posting a 2-2 mark.
Martinez (16-4) will be making his UFC debut after making it to the elimination round on The Ultimate Fighter 18.
The event is set for February 1 from Newark, New Jersey and will air on UFC Fight Pass, FOX Sports 1 and pay-per-view.
