The specific bout lineup for the quadrupleheader, featuring Al Haymon-advised fighters in each fight, was also announced.

In the co-feature, Anthony Peterson (34-1, 22 KOs), the younger brother of junior welterweight titlist Lamont Peterson, will take on Yakubu Amidu (21-5-2, 19 KOs) in the 10-round junior welterweight match.

Junior middleweight prospect Julian Williams (17-0-1, 10 KOs) will face Edgar Ortega (15-2, 10 KOs) in a 10-round bout, and in the 10-round opener, super middleweight Julius Jackson (18-0, 14 KOs) will fight Jonathan Nelson (19-1, 9 KOs).

Among the notable boxers who will appear on the non-televised part of the card, featherweight Gary Russell Jr. (24-1, 14 KOs) will fight for the first time since he was easily beaten by Vasyl Lomachenko in a vacant featherweight world title bout on June 21. Russell will face Christopher Martin (28-4-3, 9 KOs), who has lost two of his past three fights, in a 10-rounder.
