Former WEC champion Mike Brown will have a new opponent this August, as Akira Corassani has been forced out of a planned match.
In place of Corassani will be Steven Siler. The two are now set for UFC on FS1: Shogun vs. Sonnen on August 17 from Boston.
Siler (22-10) has won four of his five UFC bouts, including a recent win over Kurt Holobaugh.
Brown (26-8) is making his return to action after over a year away. He briefly thought about retiring.
