Let's take a look back at what people were talking about this week in the world of mixed martial arts:

• According to Sherdog's Josh Gross, PRIDE USA President Ed Fishman has sued Dream Stage Entertainment -- the parent company of PRIDE -- for about $10 million for breach of contract.  These monies include $1 million over five years for consulting fees and approximately $9 million Fishman feels he is owed as part of his 10 percent cut of gate receipts over the next five years for PRIDE events held in the US. Allegedly, PRIDE still hasn't paid Fishman for the past two events it held in Las Vegas (last November and this past February).
• A report by Sherdog's Greg Savage and Josh Gross appears to indicate that UFC is on the verge of buying out PRIDE in some form or another. The details and terms of the potential agreement seem a bit sketchy right now.  No official word has come down from either UFC or PRIDE about such a deal.  PRIDE is reportedly under quite a bit of financial strain and Dana White told me in a January interview that if PRIDE is for sale, he is interested in purchasing the Japanese league.
• Sherdog's Greg Savage is reporting that sources close to the situation say that Chuck Liddell will indeed be defending his UFC light heavyweight title against Quinton Jackson on May 26 at UFC 71 in Las Vegas. Jackson -- as many of you already know -- is the only fighter Liddell has fought and never defeated.
• OCRegister.com is just now reporting that Diego Sanchez failed a drug test at the December UFC fight night in which he defeated Joe Riggs.  According to the article, Sanchez tested positive for marijuana and has already paid a $500 fine and served his 3 month suspension. This means that Sanchez will still face arch-rival Josh Koscheck at UFC 69 April 7 in Houston. The revelation logically leads to a couple of burning questions.  1) Do Sanchez and Nick Diaz have the same trainer?  And 2) will their marijuana-tinged decisive victories lead others to take up their smoke and snack training regimen?
• And finally, this tidbit is not related to MMA at all but it's equally important.  I'm a University of Maryland grad so it's my obligation to share a particular video that is quite popular on YouTube right now.  Thanks to Sun columnist Rick Maese for unearthing this treasure on his blog.  I've had the video on endless loop since I first read about it Wednesday. Go to YouTube or Google and type in "This is why Duke sucks" and enjoy!  Be forewarned that the humor on the video is a bit raunchy, but it's clever nonetheless.
