It's Olympian vs. Olympian when 2008 judo bronze medalist and best female MMA fighter on planet Earth Ronda Rousey defends her UFC title on Saturday against Sara McMann, who won a silver medal for wrestling in 2004.
The timing is appropriate, given that the Winter Olympics are now in full swing in Sochi. Will UFC 170's main event honor its monolithic bloodlines? Rousey is a heavy favorite to retain the women's bantamweight strap, even if McMann has the talent to pose a threat to just about anyone.
The evening's co-main event features Daniel Cormier, a member of the 2004 and 2008 Olympic wrestling squads. His bout lost a lot of its world-class burnish when Rashad Evans pulled out last week with an injury and was replaced by Patrick Cummins.
There are plenty of other intriguing bouts up and down the card. Here is your complete guide, including information capsules on each fighter and matchup, predictions and viewing coordinates.
