Former UFC bantamweight champion TJ Dillashaw has had several huge moments throughout his career, but Saturday's Fight Night main event against Cory Sandhagen might be the biggest fight of his career -- at least in terms of perception.
Dillashaw (16-4) returns to competition for the first time in two and a half years after serving a two-year suspension for taking erythropoietin (EPO).
Dillashaw, 35, says he has moved past his mistake and is looking toward the future.
