Ronda Rousey will face off against undefeated Sara McMann in UFC 170 on Saturday in a massive UFC bout from Las Vegas.

Tonight's UFC action will start at 7 p.m. EST from Mandalay Bay Events Center in Las Vegas, Nevada with the Fight Pass Prelims. At 8 p.m. EST the Fox Sports 1 Prelims will start, leading up to the Main Card event starting from 10 p.m. EST.

Rousey will be the big favorite for tonight's match up, however, McMann is believed to be a dangerous opponent for her. The champ's Judo expertize could be tested to the max tonight as she comes up against a freestyle wrestling Olympic medalist.

Judo experts have famously found wrestling opponents slightly more challenging, and McMann should have the skills to make this a tough battle for Rousey.

Both fighters are undefeated coming into this bout, and this should be an intriguing match up for all UFC fans to get excited over.

UFC fans saw Rousey destroy Miesha Tate in UFC 168 just eight weeks ago, and although McMann doesn't have the high profile of Tate, she could prove a much more difficult fighter for Rousey to come up against.

McMann is 7-0 overall and 1-0 in UFC competition, and will attempt to bring Rousey down to the canvas and finish things quickly to avoid taking too many blows from her stronger opponent.

McMann needs to also be aware to stop Rousey from using her lethal armbar – the weapon that has disabled fighter after fighter that has come up against her over the past year.
