According to Strikeforce CEO Scott Coker, you'll get to see the preliminary cards for the next two Strikeforce events on HDNet. Along with that, you'll get to watch the weigh-ins on the network as well. Here's a quote from Mr. Coker (via MMA Nation):

"As we continue to showcase some of the sport’s up-and-coming talent on our prelims, we’re excited to be able to air them live on HDNet," Strikeforce CEO Scott Coker said. "We’re excited to give Strikeforce fans even more access to great fights."

The first event that will be given the HDNet treatment is the Strikeforce: Heavyweight Grand Prix Semi-Finals card that is scheduled for September 10th. Things change quickly in the land of Strikeforce, but these are the four fights that are currently set for the undercard:

The withdrawal of Josh Thomson from the event might mean that one of these fights moves up to the main card, but there's no way to know until Strikeforce names a replacement to compete against former Sengoku fighter Maximo Blanco. But for all those fans that crave live fights, this is very good news. The next Strikeforce event that HDNet will cover is not confirmed at this point, but with SF having a December 12th card scheduled, you can probably bet on that being the other card in question.

The main card of the September 10th event, which features both heavyweight grand prix semi-finals and a middleweight title showdown between Ronaldo "Jacare" Souza and Luke Rockhold, can be viewed on Showtime.
