Featherweight world titlist Shakur Stevenson goes up in weight to face Felix Caraballo in the main event of a Top Rank card on Tuesday at the MGM Grand Conference Center in Las Vegas.
Before that, a few good prospects will showcase their skills on the undercard.
In the co-main event, heavyweight Jared Anderson (3-0, 3 KOs) faces Johnnie Langston (8-2, 3 KOs) in a six-round battle.
Another unbeaten heavyweight, Guido Vianello (6-0, 6 KOs), meets veteran power puncher Donald Haynesworth (16-3-1, 14 KOs), and middleweight Calvin Metcalf (10-3-1, 3 KOs) faces Quatavious Cash (11-2, 7 KOs). Both fights are scheduled for six rounds.
To open the broadcast, two-time Olympic gold medalist Robeisy Ramirez will look for his third victory in a row after losing his professional debut in August. Ramirez (2-1, 2 KOs), who defeated Stevenson in the finals of the 2016 Olympics, faces Yeuri Andujar (5-3, 3 KOs) in a six-round bout.

Ramirez stops Andujar in Round 1
Featherweight Robeisy Ramirez (3-1, 3 KOs) made quick work of Yeuri Andujar (5-4, 3 KOs), needing just 54 seconds to score his third consecutive stoppage victory. A hard left on the chin in the opening seconds of the bout stunned Andujar, who went down a short time later by a follow up uppercut.
Andujar rose to his feet, but another booming overhand left from Ramirez had him down for the second time. Referee Tony Weeks immediately waved off the bout.
For Ramirez, a two-time Olympic gold medalist, who scored a victory over Shakur Stevenson in the finals of the 2016 Rio Olympic Games, it’s another indication that his shocking upset loss to Adan Gonzalez in his pro debut was perhaps just an aberration.
