If you haven’t already heard, Jason Guida is stepping in for Ken Shamrock this weekend to take on Bobby Lashley on Roy Jones Jr.’s “March Badness” card. And so far, he’s done a pretty good job filling in for Ken by adding some heat to the fight. In the video above, Guida can be seen talking a little trash to Bobby which results in Lashley grabbing Guida by the throat at the end before Jones Jr. steps in to break it up. Something tells me Lashley is the wrong guy to piss off.
