Right here, sit back and watch Showtime Boxing's Knockout of the Year candidates. They've had some great knockouts on their airwaves over the past 12 months, and with everyone else highlighting their best and biggest moments, they're doing the same. Check out the big knockouts with this Showtime Boxing video highlight reel below.

Highlights from the most memorable knockouts of SHOWTIME Boxing events from 2012. Watch brutal KOs from Gary Russell Jr. vs Roberto Castaneda, Angelo Santana vs. Johnny Garcia, Deontay Wilder vs. Kelvin Price, and Danny Garcia vs. Erik Morales.

Of course, we've already handed out our 2012 Knockout of the Year, Juan Manuel Marquez's brutal one-punch right hand counter that sent Manny Pacquiao careening to the canvas unconscious and it was from the HBO Pay-Per-View.

But definitely some good candidates here nevertheless, and it's always fun to rewatch great knockouts like these!
