If we know for sure, we'd bet big. At this point, McGregor is the underdog, but with these big-time fights, anything can happen. The experts at CBS Sports put together a helpful roundup of their staff picks, predictions and odds for Saturday night's fight.
Fox Sports will stream the weigh-in on Friday, Aug. 25, at 4 p.m. PT (7 p.m. ET, midnight UK), as well as an hour-long show prior to the fights starting on Saturday night. The first two hours of early boxing bouts will also be streamed by Fox Sports. All of which are free.
To watch the Fox live stream, you'll need to install the Fox Sports Go app on an Android or iOS device, or on an Apple TV, Android TV, Fire TV, Xbox One and Roku. Additionally, FoxSportsGo.com will stream the prefight festivities.
You don't have to have cable to stream the fight. Two options -- CBS and UFC -- will let you stream the fight on any device, including your computer, phone, tablet, TV or streaming box.
One option for streaming the fight is to purchase it directly from the UFC. This lets you stream the fight through your computer, phone, Apple TV and many more streaming devices, including the Xbox One, Amazon Fire TV, Android phones or Roku.

Breaking from the traditional means of purchasing directly from a cable or satellite provider, CBS will also make the fight available to stream on the Showtime PPV website as well as its iOS and Apple TV apps. (Disclaimer: CBS is CNET's parent company.)
For those who want to stream the fight on a computer, you can visit ShowtimePPV.com and purchase access for $99.95.

Showtime PPV is also available through the Apple TV, iPhone and iPad. Just be sure to purchase the fight on the device you plan to watch it on.
As an added bonus for those who pay to stream the fight, you will also have access to a free trial of Showtime and CBS All Access.
