It’s another UFC fight week, and with a pair of female title fights, Saturday’s UFC 193 card could be one of the biggest in company history – despite some massively lopsided odds.

UFC 193 takes place Saturday at Etihad Stadium in Melbourne, Australia, and the main card airs on pay-per-view following prelims on FOX Sports 1 and UFC Fight Pass. The 70,000-seat stadium could break the UFC’s attendance record, which was set in 2011 at Toronto’s Rogers Centre (55,724).

The sport’s biggest star headlines the card: Long-dominant women’s bantamweight champion Ronda Rousey (12-0 MMA, 6-0 UFC) looks for her seventh consecutive title defense when she takes on former boxing champion and undefeated MMA contender Holly Holm (9-0 MMA, 2-0 UFC). Rousey, a hefty 16-1 favorite heading into Saturday’s fight, is ranked No. 1 in the NOS Energy Drink MMA women’s bantamweight rankings, and Holm is No. 9.

In the co-headliner, strawweight champion Joanna Jedrzejczyk (10-0 MMA, 4-0 UFC), a massive 21-1 favorite, looks for her second title defense when she takes on Valerie Letourneau (8-3 MMA, 3-0 UFC). Jedrzejczyk is ranked No. 1 while Letourneau is No. 7 in the 115-pound division.

How lopsided are the odds for the two title fights? If victorious, a $100 bet on Rousey would net you $6.25. For Jedrzejczyk, a winning $100 bet would result in a profit of just $4.76. (The odds, though, are likely to fluctuate throughout the week.)

Also on the the main card is a rematch between New Zealand-born and Australian-based heavyweight Mark Hunt (10-10-1 MMA, 5-4-1 UFC) and Brazilian veteran Antonio Silva (19-7-1 MMA, 3-4-1 UFC). Hunt, who’s ranked No. 10 in the division, and No. 14-ranked Silva fought to a majority draw at a 2013 UFC event in Australia.

Rounding out the main card are No. 11 middleweight Uriah Hall (12-5 MMA, 5-3 UFC) vs. Robert Whittaker (14-4 MMA, 5-2 UFC) and No. 11 heavyweight Stefan Struve (26-7 MMA, 10-5 UFC) vs. Jared Rosholt (13-2 MMA, 5-1 UFC).

The featured prelim includes Australian lightweight Jake Matthews (8-1 MMA, 2-1 UFC) vs. Akbarh Arreola (23-9-1 MMA, 1-2 UFC).
