Thomas & Mack Center,Las Vegas - Olympian Robson Conceicao (1-0), who won a gold medal in Rio, made his pro debut with a six round unanimous decision over Clay Burns (4-4-2). All three judges saw it 60-54.

Welterweight prospect Alexander Besputin (5-0, 5KOs), who is trained by Robert Garcia, stopped Azael Cosio (20-5-2, 17KOs) in six rounds. The contest took place at a catch-weight of 150-pounds.

Besputin controlled the fight, but he was stunned on at least two occasions. He broke Cosio down, round by round, and he was unable to come out for the seventh. 

Lightweight prospect Teofimo Lopez (1-0, 1KO) made his pro debut with a second round knockout of Ishwar Siqueiros (3-2-1).

A right hand right down the middle sent Siqueiros down for a flash knockdown in the first. A moment later he scored a second knockdown with a winging right hand to the jaw. But then Lopez got too wild at the end of the round while hunting for a knockout and seemed to get hit while off-balance - which led to his glove touching the floor and a knockdown being called.

In the second round, a series of punches sent Siqueiros down for a third time. He was allowed to continue but soon went down again for the full count.

A featherweight contest opened up the card, Fernando Fuentes (10-7, 3KOs) shocked Que Xu (9-2-1, 2KOs) of China with a six round unanimous decision. The scores were 58-56, 58-56, 58-55. Fuentes landed the better eye catching shots and outworked Xu during crucial spots.
