Conor McGregor (19-3) underestimated Nate Diaz (19-10) the first time they met in the headlining welterweight matchup at UFC 196 back on March 5.
On Saturday, McGregor will not be overlooking Diaz and will instead be seeking revenge in the rematch as a small -130 betting favorite (wager $130 to win $100) at sportsbooks monitored by Odds Shark.
McGregor held his own in the first round of his first career bout at 170 pounds, 25 more than he typically fights at as the reigning featherweight champion. But in the second round, the bigger Diaz took advantage of a fatigued McGregor and submitted him via rear-naked choke to pull off what was a sizable upset.
