UFC fighter Desmond Green is facing four DUI manslaughter charges for his alleged role in a five-vehicle crash last August that killed two people.

He has pleaded not guilty and is out on $194,000 bond, his attorney, James Benjamin, told ESPN on Wednesday. Green has requested a jury trial.

According to Broward County Jail records, Green, 29, was arrested Tuesday. Along with the manslaughter charges, the Broward County Court lists 19 total charges, including DUI causing serious bodily injury (four counts), DUI causing property damage (five counts), operating with a suspended license, and possession of cocaine, marijuana and drug paraphernalia.

"They've alleged that he caused the crash and was over the legal limit of alcohol at the time. We are going to contest that," Benjamin said. "The testing that they did on his blood alcohol level wasn't until hours after the crash and we don't think it's valid. He has been patiently awaiting the state attorney's office to make a determination for almost a year. It's a tragic situation where two people passed away and we're just so sorry that happened but, quite frankly, we don't think it is Desmond's fault."

In August, Alvaro Feola, a spokesman for the Florida Highway Patrol, told reporters that Green lost control of his Dodge Durango just before 6:15 a.m. on Interstate 75 in Davie, Florida. The SUV veered into the path of a tractor-trailer, causing a chain-reaction crash with three other vehicles.

Two people -- Emelina Morfa, 67, and Emma Suarez Hernandez, 76 -- were killed. Two others were seriously hurt. Green suffered minor injuries.

Green (21-7) has fought three times since the crash, winning his last two bouts.
