On Unlocking Victory, Dominick Cruz breaks down how Conor McGregor set up his knockout win vs. Dustin Poirier in 2014. (1:04)

Conor McGregor is back. After a total of 40 seconds of fight time in 2020, McGregor returns Saturday at UFC 257 to begin the next stage of his career. But unlike his fight last January, his opponent isn't a past-his-prime Donald Cerrone. McGregor will be up against a tough foe in Dustin Poirier, who is coming off a strong performance against Dan Hooker.
