“I’m excited to be fighting at The Hangar and on ESPN as I continue my quest to become the heavyweight champion of the world,” Pulev said. “I have a great team behind me, and I am focused and ready to take care of business on March 23.”

“I know this is a big opportunity for me to get to the top of the heavyweight division,” Dinu said. “I am happy to be fighting in the United States against a really top heavyweight in Pulev. When I win, I will be considered a top contender.”

“I haven’t fought in a long time, but I am ready to show the fans that I am the same guy who won the title not too long ago,” Magdaleno said. “I feel comfortable in my new weight class, and now that I’m back, the goal is to become a two-weight world champion.”

“I’m thrilled to be fighting on ESPN,” Ramos said. “I would like to thank Top Rank for the opportunity to showcase my skills on boxing’s biggest stage. I’m preparing my best to give the fans a great show. This fight will get me one step closer to becoming a two-time world champion.”

Pulev (26-1, 13 KOs) is closing in on a second world title shot, the first coming in 2014 when he put up a valiant effort before being stopped by longtime champion Wladimir Klitschko in the fifth round. He has won six straight since the Klitschko loss, most recently defeating fellow contender Hughie Fury via unanimous decision in front of his hometown fans at the Arena Armeec in Sofia, Bulgaria. Dinu (18-1, 14 KOs), a one-time top amateur in his native Romania, will be making his second ring appearance in America. He is looking to bounce back from a fourth-round stoppage loss to Jarrell Miller.

Magdaleno (25-1, 18 KOs) will be fighting for the first time since Isaac Dogboe snatched the WBO junior featherweight world title from him last April in a Fight of the Year contender. Dogboe bounced back from a first-round knockdown to stop Magdaleno in the 11th round. Magdaleno, who had difficulty making the 122-pound limit, hopes a win over Ramos propels him toward a featherweight world title shot.

Ramos (30-5, 14 KOs) captured the WBA super bantamweight title on July 9, 2011 in Atlantic City with a stunning one-punch knockout of Akifumi Shimoda. He lost the title the following January to Guillermo Rigondeaux via sixth-round knockout. Ramos has been on a hot streak since a 2015 knockout loss to Claudio Marrero, winning six in a row while campaigning at both super bantamweight and featherweight. He won a pair of fights in 2018, including an eight-round unanimous decision over Daniel Olea last September that streamed on ESPN+.
