Prograis (20-0, 17 KOs), of Houston by way of New Orleans, has scored knockouts in 13 of his last 14 fights and is a rising star in the wide-open 140-pound division. The aggressive-minded southpaw will face the toughest test of his career in Postol, a former WBC Super Lightweight World Champion with only one loss on his record.

In the 12-round co-feature, undefeated 140-pound contenders Ivan Baranchyk (17-0, 10 KOs) and Anthony Yigit (21-0-1, 7 KOs) will square off in a Junior Welterweight World Title Eliminator to become the mandatory challenger for IBF champion Sergey Lipinets. Lipinets will defend his belt the following day, March 10, on SHOWTIME CHAMPIONSHIP BOXING® against undefeated three-division champion Mikey Garcia.
