The fighters tipped the scales earlier tonight (Fri., Jan. 27, 2017) in preparation for UFC on FOX 23 tomorrow (Sat., Jan. 28, 2017) live on FOX from inside the Pepsi Center in Denver, Colorado. In the main event of the evening, women's bantamweight title threats Valentina Shevchenko and Julianna Pena will duke it out for No. 1 contender rights. Check out their weigh ins staredown here.

In the co-main event of the evening, Donald Cerrone and Jorge Masvidal will lock horns in a potential Fight of the Night matchup. Cerrone and Masvidal have talked a little trash leading up to their welterweight bout and continued chirping during the weigh ins. Ultimate Fighting Championship (UFC) president Dana White captured some of the banter and threw it up on Twitter moments later (shown above).

The only left to do is bust each other "right in the f--king mouth."
