The UFC returns this Saturday with one of the biggest events in the history of the organization, as bantamweight champion Ronda Rousey puts her belt on the line in front of potentially the largest UFC crowd ever at UFC 193 in Melbourne, Australia.

In the co-main event, feared striker and strawweight champion Joanna Jedrzejczyk defends her title for the second time when she takes on Valerie Letourneau. Jedrzejczyk has some of the best boxing in all of MMA, and has outstruck her last two opponents 179-29 in significant strikes. Letourneau, however, has won three straight since joining the UFC and has some of the best striking defense in the weight class.

The rest of the card is filled with exciting fights, including a rematch of one of the greatest heavyweight fights of all time and a matchup between dynamic middleweights Uriah Hall and Robert Whittaker. Not to mention 21-year-old Aussie, Jake Matthews, headlining the FS1 prelims card.

But before all these fighters can lay hands on each other, they must make weight. So stick with us through all the weigh-in action and check us out Saturday for a full slate of UFC 193 coverage.
