Here's a look at the 16 participants:
• Ievgen Khytrov (16-1, 13 KOs), 29, a native of Ukraine fighting out of Brooklyn. A former top prospect who has won two fights in a row since he was upset by Immanuwel Aleem via sixth-round knockout in 17 months ago.
• Eric Walker (15-1, 8 KOs), 34, of Plaquemine, Louisiana. Incarcerated at 15 years old, he spent 14 years in prison for robbery and attempted murder. He learned to box in prison. He's coming off his first loss, a 10-round decision to Patrick Day last July.
• John Thompson (18-3, 6 KOs), 29, of Newark, New Jersey. He won the 2015 ESPN Boxcino junior middleweight tournament, a win that landed him a vacant world title shot later in the year that he lost by seventh-round knockout to Liam Smith.
• Brandon Adams (17-2, 12 KOs), 28, of Los Angeles. He lost in the final of the 2014 ESPN Boxcino middleweight tournament and then won three fights in a row before losing to Thompson in the final of the 2015 ESPN Boxcino junior middleweight tournament. Adams has not fought since.
• Malcolm McAllister (9-1, 8 KOs), 27, of Long Beach, California. He turned pro in 2014 and is coming off his first loss, an eight-round decision to unbeaten prospect Chordale Booker.
• Quatavious Cash (10-0, 7 KOs), 26, of Las Vegas. The Atlanta native turned pro in 2012 but had a three-year layoff before returning in 2017. He's a four-time Golden Gloves state champion.
• Shane Mosley Jr. (10-2, 7 KOs), 27, of Santa Monica, California. He's the son of former pound-for-pound king and three-division champion Shane Mosley. He has not fought since an eight-round split-decision loss in Australia on the Manny Pacquiao-Jeff Horn undercard.
• Daniel Valdivia (14-2, 10 KOs), 25, of Tulare, California. A real estate agent by day, he's moving up in weight after consecutive eight-round decision losses to Vladimir Hernandez in his last two fights.
• Michael Moore (15-1, 7 KOs), 31, of Cleveland. He participated in the 2015 ESPN Boxcino junior middleweight tournament but lost in the quarterfinals. He's fought only twice since, but won both bouts.
• Gerald Sherrell (8-0, 4 KOs), 24, of Pittsburgh. He's a prospect who has been fighting four- and six-rounders. He grew up as a fan of the original "Contender" series.

• Marcos Hernandez (11-1, 3 KOs), 24, of Fresno, California. Hernandez has yet to face any name opposition but he has overcome a lot in life after an accident left him with burns on 30 percent of his body, which led him to be bullied as a child. He's raising an autistic son.
• Tyrone Brunson (26-6-2, 24 KOs), 33, of Philadelphia. He began his career with 19 consecutive first-round knockouts and is one of the most experienced fighters in the field. He knocked out former welterweight titlist Kermit Cintron last year.
