Chael Sonnen, who fell just short of dethroning longtime UFC middleweight champion Anderson Silva at this past month’s UFC 117 event, failed his post-fight drug screening due to performance-enhancing drugs.
That’s according to California State Athletic Commission Executive Officer George Dodd, who alerted Sherdog.com of the failed test.
