On tonight's episode of Monday Night Raw, former SmackDown Commissioner Shane McMahon introduced a new concept called "Raw Underground."

This new concept appears to be based on no-holds-barred-style mixed martial arts fighting. As fans might be aware, Shane has legitimately been a longtime fan of mixed martial arts for many years, going back to the early days of the Ultimate Fighting Championship and the old Japanese PRIDE Fighting Championships.

Here are some clips of Raw Underground from WWE's Twitter account:
