I don't know what it is, but these free Spike cards for the troops always seem to provide the kind of moments that permanently entrench themselves into your cerebrum. The UFC has put on two such events to date and have already provided MMA gold. Who can forget Diego Sanchez knocking out Joe Riggs at UFC: Fight Night 7? How about the Corey Hill leg break or Josh Koscheck's first round KO over Yoshiyuki Yoshida at UFC: FIght Night 16? Absolute classics. Let's hope the fellas performing tonight can add to the legacy.
Stay tuned to SB Nation MMA as we break down the main card and try to make sense of our predictions.
