A trio of exciting local prospects will compete in their hometown as 2016 Haitian Olympian Richardson Hitchins (2-0, 1 KO) fights in a four-round welterweight bout, Brooklyn's Julian Sosa (9-0-1, 3 KOs) enters the ring for a six-round welterweight attraction and unbeaten prospects square-off for eight rounds of super welterweight action as Brooklyn's Chordale Booker (7-0, 4 KOs) meets Malcolm McCallister (9-0, 8 KOs).

Rounding out the night of fights are Justin Hurd (3-0, 3 KOs), brother of 154-pound champion Jarrett, in a six-round super welterweight bout against Georgia's Steven Andrade (3-2, 2 KOs) and unbeaten Dylan Price (3-0, 3 KOs) in a four-round junior bantamweight affair.

The 27-year-old Harrison scored an explosive ninth-round stoppage of Sergey Rabchenko last July at Barclays Center to earn his world title shot earlier this year in which he lost a spirited contest against Jarrett Hurd. The Detroit-native was unbeaten in his first 21 pro fights, recording 10-straight knockouts between 2013 and 2015 and owns victories over Cecil McCalla, Fernando Guerrero and Tyrone Brunson over his seven-year pro career. He will take on the 30-year-old Valenzuela Jr. out of Baja California Sur, Mexico who has won three of his last four contests.

The older sister of five-division champion Amanda, Cindy became a world champion last year when she defeated Calixta Silgado to capture the WBO Featherweight World Championship. Born in Puerto Rico but raised and fighting out of Brooklyn, she defended her title successfully in May by defeating Paola Torres. Serrano is unbeaten in her last 12 contests dating back to 2012 and will be making her Barclays Center debut on October 14.
