Despite dropping the first meeting, Conor McGregor will still likely enter UFC 202 Saturday night as the betting favorite.
The reigning UFC featherweight champion will meet Diaz in a non-title fight at welterweight. Diaz won the first encounter with a second round submission earlier this year.
According to Bookmaker.eu, McGregor is currently a -123 favorite, with Diaz coming in as the underdog at +103.
The odds are very close between co-main event fighters Anthony Johnson (-195) and Glover Teixeira (+166), along with Donald Cerrone (-165) and Rick Story (+140).
The other two main card welterweight bouts, though, are lopsided, with Tim Means and Hyun Gyu Lim heavily favored.
