The 25-year-old González (25-0-1, 13 KOs) made a successful U.S. debut on Showtime in May 2022, earning a unanimous decision over Emanuel Rivera Nieves in their 10-round fight. A native of Sinaloa, Mexico, González has fought professionally since 2016, and owns a unanimous decision over former title challenger Ivan Morales in March 2021. González won a regional 122-pound title by stopping Alexander Mejia in July 2021, finishing the fight in round seven. He takes on the 30-year-old Sanmartin (34-6-1, 21 KOs), who most recently won a unanimous decision over Miguel Martinez in December 2022. The Arboletes, Colombia-native has challenged current featherweight champion Mauricio Lara and current super featherweight champion Emanuel Navarrete during a pro career that dates back to 2011.

A native of Cuba now residing in Miami, Velazquez (6-0, 6 KOs) has stopped each opponent he’s faced since turning pro in October 2020 following a prolific amateur career.

He will be opposed by Buenos Aires, Argentina’s Lopez (37-2-1, 22 KOs), who enters this fight having won his last five outings, including triumphs over veteran contenders Pablo Cesar Cano and Breidis Prescott. The 36-year-old has a 5-1 record stateside, with his only blemish coming via-split decision against Michael Perez in 2017.
