Lomachenko (16-2, 11 KOs) returns after serving a stint in a territorial defense battalion in his native Ukraine, a decision that delayed his quest for undisputed glory. Ortiz (16-0-1, 8 KOs) authored a career-best victory over former world champion Jamel Herring in May.

The 10-round featherweight co-features sees Cuban two-time Olympic gold medalist Robeisy Ramirez (10-1, 6 KOs) attempt to move closer to a title shot against late substitute Jose Matias Romero (26-2, 9 KOs).

Undercard action includes middleweight prospect Nico Ali Walsh (6-0, 5 KOs) and a quartet of U.S. Olympians from the Tokyo Games: silver medalists Duke Ragan (7-0, 1 KO) and Richard Torrez Jr. (3-0, 3 KOs), Tiger Johnson (5-0, 4 KOs), and Troy Isley (7-0, 4 KOs).
