Rivera (26-2-2, 17 KOs) is no stranger to stepping into tough challenges on short notice. One of his losses came when he stepped in as a late replacement to take on Joseph "JoJo'' Diaz in September 2017 and lost by decision. In his next fight he lost a split decision to unbeaten Joet Gonzalez on July 13. He rebounded with a knockout victory over Jose Ramos in his last fight on October 19 and will now step up to face the toughest challenge of his career on February 16.



At 6-foot-6, the unbeaten Fundora (11-0, 7 KOs) has made a name for himself with his stature and skills inside the ring. The 21-year-old southpaw from Coachella, California blazed through 2018 by stopping all three of his opponents by knockout, including previously unbeaten Ve Shawn Owens in April and most recently Jeremiah Wiggins in November.



The 30-year-old Marshall (10-0, 6 KOs) is from Raleigh, North Carolina and also had a busy 2018, fighting four times and scoring two stoppage wins. He earned unanimous decision over Javier Frazier in his last fight on November 30.
