Gonna go to Mississippi San Joaquin County ... Gonna See Miss Liza...

Ultimate Fighting Championship (UFC) welterweight Nick Diaz reported for jail earlier today (Thurs., Sept. 3, 2015), according to TMZ, after pleading guilty last month to driving under the influence (DUI). That's the bad news. The good news?

He'll be back on the streets by tomorrow morning.

Diaz was picked up just over a year ago and in addition to his boozing charge, was also booked for obstructing a police officer, destroying evidence, and driving with a suspended license (mugshot here). Once he finishes his business behind bars, the Stockton slugger must complete a DUI educational course in order to avoid harsher penalties.

Easy-peasy.

The former welterweight No. 1 contender hasn't been seen since dropping a unanimous decision to Anderson Silva back in January -- for which he also tested positive for marijuana -- and continues to drag out his legal fight with Nevada State Athletic Commission (NSAC).
