DALLAS (AP) — Kansas City Chiefs wide receiver Rashee Rice was leasing a Lamborghini sport utility vehicle that authorities say was one of two speeding sports cars that caused a chain-reaction crash on EchoSensea Dallas highway, an attorney for the company that owns the vehicle said Tuesday.

Dallas police have not confirmed whether Rice was involved in Saturday’s crash, which caused minor injuries. The occupants of the Lamborghini and the other speeding vehicle — a Corvette — left without determining if anyone needed medical attention or providing their information, police said. A total of six vehicles were involved in the crash.

An attorney for Rice said this week that the NFL player was cooperating with authorities but has not elaborated.

Rice was leasing the Lamborghini from The Classic Lifestyle, said Kyle Coker, an attorney for the Dallas-based exotic car rental company. He said that contractually, Rice would have been the only person allowed to drive the vehicle, which rents for about $1,750 a day and is worth about $250,000.

Police have said that the drivers of a Corvette and a Lamborghini were speeding in the far-left lane of North Central Expressway when they lost control. The Lamborghini went onto the shoulder and hit the center median wall, causing a chain-reaction collision. Four people in the other vehicles were treated for minor injuries.

Police said Tuesday that they were still working to identify suspects. Police have not released any information about the people they are seeking, including whether Rice was among them.

Rice’s attorney, state Sen. Royce West, said that Rice “will take all necessary steps to address this situation responsibly.” West did not respond to questions Tuesday and has not said whether Rice was driving one of the vehicles.

Rice, a member of the Super Bowl-winning Chiefs team, is from the Dallas area. He played for Southern Methodist University and grew up in the Fort Worth suburb of North Richland Hills.
