Since making his film debut in last year's Creed,the latest installment of the internationally recognized Rocky franchise, "King" Gabe Rosado is fresh off of an exciting victory over Joshua "Grand Master" Clottey this past December 2015 and an exciting decision victory over Antonio "Tony" Gutierrez on the undercard of Fight of the Year contender Vargas vs. Salido on June 4. Rosado has established himself as one of the most entertaining fighters to watch in the sport taking on some of the toughest and elite fighters in the middleweight division. The epitome of Philadelphia toughness, Rosado has been battling the best for over a decade, including Gennady "GGG" Golovkin, David Lemieux, Peter "Kid Chocolate" Quillin, Jesus Soto "Renuente" Karass, Alfredo "Perro" Angulo, Kassim "The Dream" Ouma and Jermell "Iron Man" Charlo. But this September, Rosado, expects to leave Texas with a victory under his belt when he takes on Willie Monroe, Jr.

Willie began boxing at the age of six and comes from an acclaimed boxing family, which includes his father, Willie "The Body Rock" Monroe, who fought for the USBA and NABF titles at middleweight and super middleweight; his great uncle Willie "The Worm" Monroe (39-10-1) who was considered one of the best Middleweights of the 1970's and holds a win over the great Marvin Hagler; his cousin Marcus Hall (6-6-1), and his late grandfather, Lee Monroe, a distinguished amateur in his fighting days. Willie had a distinguished amateur career, as well, which saw him go 128-14. He was a three-time national champion and won countless regional and state championships. He was a 2-time Empire State Games champion and 4-time State Golden Gloves champion. He lost in the quarterfinals of the 2008 Olympic trials to former IBF Welterweight champion Shawn Porter. Willie's big breakthrough was winning the 2014 Boxcino Middleweight tournament on ESPN's Friday Night Fights. Willie then took a ten-round unanimous decision win over perennial contender Bryan Vera on January 16, 2015 from Turning Stone Resort Casino in Verona, New York. With this impressive run of victories, Willie earned an opportunity to fight for the WBA Middleweight title of the world. On May 16, 2015, Willie took on WBA/Interim WBC Middleweight champion Gennady "GGG" Golovkin in a bout that headlined HBO Championship Boxing at The Forum in Inglewood, California. In his last bout on June 11, 2016, Willie scored two knockdowns and went on to win an impressive ten-round unanimous decision over 2015 Boxcino Junior Middleweight Champion John Thompson. The bout took place at the Turning Stone Resort Casino in Verona, New York.

A member of the 2012 United States Olympic team, Joseph "Jojo" Diaz, Jr. has been seen as a future world champion for years, and now the NABF Featherweight Champion is closing in on that dream. Currently ranked third in the world by the WBC and ninth by the IBF and WBO, the 23-year-old southpaw from South El Monte, California has steadily moved through all opposition at 126 pounds, including Rene "Gemelo" Alvarado, Ruben "Canelito" Tamayo and Hugo "Guerrero" Partida. But it was in his March 26 win in his HBO debut over highly-regarded Jayson "La Maravilla" Velez that Diaz announced his arrival to the world stage. Diaz, Jr. was last seen in the ring against Victor "Pitufo" Proa defeating the fighter via second round knockout as the co-main event to Anotnio Orozco vs. Abner Lopez live on HBO Latino Boxing, on July 30.  Now, set to face one of the hardest punchers in his division, Diaz, Jr. is ready to move up to the big leagues when he faces Andrew "El Chango" Cancio on the pay-per-view undercard of Canelo vs. Smith on September 17.

Blythe, Calif. native Andrew "El Chango" Cancio made his professional debut in 2006, remaining undefeated for ten bouts before his first loss. Cancio's power has brought him thirteen of seventeen wins by way of knockout, a strength he brought to the ring against Nicaraguan warrior Rene "Gemelo" Alvarado and former two-time world champion Hugo Fidel "El Increible" Cazares via knockout at Fantasy Springs Resort Casino, in Indio, Calif. With these impressive victories, Cancio hopes to pursue his goal of becoming a featherweight world champion as he takes on one of the toughest challenges of his career in the decorated Joseph "Jojo" Diaz, Jr on September 17.

The latest boxing phenomenon to emerge from Mexico, 22-year-old Diego De La Hoya has all the tools to become a global superstar, but the mature super bantamweight is keeping his focus on what's in front of him. In 2015, De La Hoya began his move on the super bantamweight elite with five wins highlighted by back-to-back victories over former world title challengers Manuel "Suavecito" Roman and Jesus "Estrella" Ruiz, Ramiro "Zurdo" Robles, Jose "Hollywood" Estrella, and Giovanni "Lloviznas" Delgado; winning the WBC Youth World Title in the process. De La Hoya kicked off 2016 in style in February with a fourth-round body shot knockout of Arturo "Fuerte" Badillo and successfully defending it on May 7 of this year with a blistering seventh round technical knockout of Rocco Santomauro. Now his eyes are on a big win in September at AT&T Stadium.

Puerto Rican native Orlando "Orlandito" Del Valle comes from a boxing linage that includes former WBO Bantamweight World Champion Rafael Del Valle. Prior to his professional debut on April 11, 2008 at the Tropicana Hotel and Casino in Atlantic City, New Jersey where he knocked out Rey Rivera in the third round, Del Valle was an Under 19 National Junior Olympic Champion for Puerto Rico, three-time New York Golden Gloves Champion, National Golden Gloves Champion, and U.S. Boxing's number one rated junior boxer at 125 lbs. Now, Del Valle is riding a four fight win streak with two victories already notched in 2016. In his first contest of the year on April 9, Del Valle scored a second round technical knockout victory over rising prospect Josh Crespo at Rockingham Park in Salem, New Hampshire. He followed that performance with an eight-round unanimous decision victory over southpaw veteran Thomas "KO" Snow on May 13 as the nationally televised co-feature of Dustin Harrison-Hernandez vs. Mike Dallas Jr. at the DC Armory in Washington, D.C. Del Valle looks to continue his momentum for a fifth consecutive win on September 17 in Dallas, Texas at AT&T Stadium
