Even before his days in the UFC, 32-year-old Chris Leben struggled to maintain emotional stability.
Emotional issues resulted in multiple DUI’s, a pair of failed drug tests and a cluster of other troubling personal problems for "The Crippler."
Leben first got arrested for DUI while on probation in April 2008 and had to serve 35 days in jail.
Less than six months later, Leben tested positive for stanozolol after dropping a unanimous decision to Michael Bisping at UFC 89.
Jake Rosholt then choked Leben unconscious in his next fight at UFC 102, a setback that sparked a three-fight winning streak for "The Crippler" that included wins over Aaron Simpson (TKO) and Yoshihiro Akiyama (triangle choke). Sherdog.com named Leben the 2010 comeback fighter of the year for his efforts following the stanozolol incident.
Another DUI arrest caused Leben to regress in the Octagon again as he suffered a TKO loss at the hands of Brian Stann shortly after at UFC 125.
True to form, Leben responded with an impressive KO of Wanderlei Silva at UFC 132, only to get TKO'd in his next bout by Mark Munoz at UFC 138 in a fight that he tested positive for painkillers.
As emotionally unstable as they come, expect Leben, who's dropped his last two fights, to roar back again—and then later repeat his ruthless cycle.
