Although headliner Gary Russell Jr. suffered a cut this week and was forced to withdraw from his initial featherweight world title defense against Oscar Escandon, the network announced on Thursday that there will still be a card that night at the Hard Rock Hotel & Casino in Las Vegas. However, rather than an edition of “Showtime Championship Boxing” headlined by Russell-Escandon, the broadcast will now be an edition of prospect-oriented “ShoBox: The New Generation.”
