Juan "The Baby Bull" Diaz will make his return to ShoBox: The Next Generation on the Showtime network Aug. 24, but not as a fighter—he will be working as an announcer on the broadcast. Diaz will be taking the place of the now-disgraced former world champion and regular commentator Antonio Tarver (29-6-1 20 KO's) whom the network has taken off the air until his failed PED test situation is cleared up.

Tarver tested positive for an anabolic steroid in a pre-fight test conducted by the CSAC before his June 2, 2012, draw against Lateefe Kayode (18-0-1 14 KO's). The fight, which appeared on Showtime, saw Tarver come back from a lackluster start to eke out a draw against his much younger undefeated opponent.

Diaz is the former undisputed lightweight champion having unified the WBO, IBF and WBA titles. He is also no stranger to ShoBox or Showtime Championship Boxing, having appeared on both shows a combined eight times in his career.

Diaz turned pro at the tender age of 16, while still in high school, but he did not let boxing get in the way of his academics as he went on to graduate from both high school and the University of Houston.  He accomplished this while fighting at the highest level and winning his first world championship while still in school.

During his career, Diaz fought the best of the best in his division. He went toe to toe with Juan Manuel Marquez on two occasions, with their first fight being named fight of the year in 2009. He also faced two-time and current WBA welterweight title-holder Paulie Malignaggi twice along with a host of other notable fighters.

Diaz retired from in-ring action at the age of 27 in 2010, but he hasn't totally stepped away from boxing. He hosts a boxing radio show on ESPN 1180AM in Houston that can be heard every Friday at 1 pm.
