MMA fans figured something was up with Jose Canseco's strong push for a Herschel Walker fight under the Strikeforce banner. And now we have a better understanding of just what that might be. The former Major League Baseball (MLB) player and the main man behind their steroid era reportedly owes the IRS $320,000.

Life post-baseball has clearly been and up and down, well ... mainly down, for the steroid stool-pigeon. After the Cuban released his tell-all book titled Juiced in 2005, he transformed into MLB's public enemy number one. 

Many of Canseco's recent endeavors have been financially driven. He was a cast member of VH1's reality show The Surreal Life - not exactly a show where self respecting people appear - and has since been involved in several "celebrity" boxing matches, having fought to a three round majority draw against former child star Danny Bonaduce in 2009.

But it looks like Canseco's compensation during his major league career - more than $45 million - as well as the money he received during his "reality star" career has run dry.

Here's a list of the former Bash Brother's pending liens, courtesy of the Detroit News:

-The IRS filed a $121,209 lien against Canseco on Jan. 7 with the Los Angeles County Recorder of Deeds.
-The state of California filed a $101,037 lien on June 2, 2009, in Ventura County Court.
-The state of California filed a $29,739 lien on Dec. 12, 2008, in Los Angeles.
-The state of California filed a $68,210 lien on July 7, 2008, in Los Angeles.

So without going as far as saying that this is the sole reason for his foray into mixed martial arts, one can easily come to their own conclusion as to why Canseco stepped into the ring against Hong Man Choi last spring.

And one can probably assume that the reason behind his re-entry into MMA in an effort to fight another former professional athlete in Herschel Walker is at least partially financially driven.

But we really shouldn't be surprised by this new revelation. His recent pattern of behavior screams that the guy is in need of money and is willing to do just about anything to get it. Here's hoping that a fight with Herschel Walker isn't one of them.
