Court records show that Green, who competes as a lightweight for the UFC, was arrested Tuesday in Broward County.
Florida Highway Patrol says Green lost control of his SUV while driving on Interstate 75 near Pembroke Pines in August 2018. It started a chain reaction crash involving five vehicles. Two passengers in one of the other vehicles, 67-year-old Emelina Morfa and 76-year-old Emma Suarez Hernandez, both died. Several others were injured.
Investigators noted that Green showed signs of impairment after the crash and reported finding drugs in his vehicle.
Green's attorney, Jamie Benjamin, says they plan to fight the charges. He says a blood sample that showed alcohol and drugs in Green's system was taken several hours after the crash and questions whether Green even caused the collision.
Green faces multiple counts of driving under the influence, as well as cocaine possession, marijuana possession and driving with a suspended license. He was being held on $194,000 bond.
The 29-year-old Green has appeared in seven fights with the UFC since joining the promotion in 2017, going 4-3. He has fought three times for the UFC since the car crash occurred in August 2018, including a bout just four weeks after the crash in September.
Green last fought May 18, winning a decision over Charles Jourdain. That UFC Fight Night bout was in Rochester, New York, Green's hometown.
The former University of Buffalo wrestler also has fought for the Bellator and Titan FC promotions since turning pro in 2012, losing a featherweight title fight for Bellator and briefly holding Titan FC's featherweight belt.
