With Matthew Riddle recently forced out of the bout with a knee injury, welterweight Ryan Thomas (9-2 MMA, 0-1 UFC) will instead meet veteran fighter and "The Ultimate Fighter 7" cast member Matt Brown (7-7 MMA, 1-1 UFC) at next week's UFC 91 event.
Now is the time for Matt Brown to step up and show his skills just like Petruzelli did against Kimbo.
