Tonight at 9 pm ET on FS1, Premier Boxing Champions returns for a Tuesday night card from Las Vegas, with a featherweight main event featuring two unbeaten prospects.

Cuba’s Leduan Barthelemy (13-0, 7 KO), the younger brother of Yan and Rances Barthelemy, will be one-half of that main event, taking on Mexico’s Eduardo Ramirez (20-0-2, 7 KO). Barthelemy, 28, is the favorite, but in a matchup like this where neither has been seriously tested, we could see anything. The fight is set for 10 rounds.

A pair of eight-round fights will take place on the undercard. In the super featherweight division, Alejandro “Popo” Salinas (8-1, 8 KO) will face Duarn Vue (12-0-2, 4 KO). In the lightweight division, Bryan Figueroa (12-0, 5 KO) will take on Ivan Jimenez (7-0-1, 4 KO).

If you’re watching the fights tonight, here’s the place to discuss all the action from these six young fighters.
