Is delirium a common ailment amongst UFC fighters? Apparently driving like a jackass may be. Now it's only two instances, Quinton Jackson (pictured during his July arrest) and Josh Neer, but the cases are eerily similar.

Ultimate Fight Night 17 co-main event fighter Neer was arrested in Des Moines earlier this morning.  A Polk County (Iowa) police report says that Neer hit a police car and engaged the cops in a 15-minute car chase. Neer was finally stopped when his car hit "stop sticks".

The Des Moines Register describes the incident and chase:

Just after midnight, a squad car on routine patrol was stopped for a red light on Court Avenue when the car behind rear-ended it, according to a written report. The woman told police her car was also struck from behind.

The 25-year-old male driver in the third car, a black Audi Quattro, then pulled out, crossed into oncoming traffic on Court Avenue, and turned north on Fourth Street, the police report stated.

Police chased the Audi 20 miles.

At Sixth and Euclid avenues, the officer attempted a stop the fleeing car by hitting the back right quarter panel with the front left side of the squad car, a technique known as a precision immobilization technique, or PIT maneuver.

The Audi spun around but the driver regained control and continued west on Euclid Avenue.

Des Moines police continued the chase as the Audi traveled into Urbandale, then onto Interstate Highway 80 eastbound. The Audi reached speeds in excess of 100 mph in a 65 mph zone, the police report says. The chase ended at mile marker 137.

Neer was released on $7,000 bail and charged with eluding the police and operating a vehicle while intoxicated. Delirium was the explanation for what fueled Jackson's driving rampage in Southern California back in July.

The Atlantic did a nice job of recapping the aftermath of Jackson's chase and capture:

“I called (UFC owner) Lorenzo (Fertitta) and our attorney at three in the morning, after I saw Rampage that night, and I’m like, ‘You guys have no (expletive) idea what I just saw. You have no idea what I just saw,’” said UFC president Dana White about visiting Jackson in jail.

The next day, the police went to Jackson’s home and took him to a psychiatric ward, where he was held for 72 hours. The immediate diagnosis was that the fighter was suffering from delirium induced by severe dehydration, reportedly caused by a week of staying up all night on energy drinks. When he was arrested, he hadn’t eaten or slept in four days.

The UFC did not suspend or penalize Jackson. He simply took five months off before winning his comeback fight at UFC 92 against Wanderlei Silva.

Will the UFC wait for the system to process Neer's incident or does it need to send a message and take him off the high profile SpikeTV Feb. 7 main event against Mac Danzig?
