Kansas City Chiefs wide receiver Rashee Rice is cooperating with authorities in Dallas after a speeding Corvette and Lamborghini sport utility vehicle caused a chain-reaction crash on a busy Dallas highway Saturday, according to his attorney.

"On behalf of Rashee Rice, his thoughts are with everyone impacted by the automobile accident on Saturday," attorney Royce West said in a statement. "Rashee is cooperating with local authorities and will take all necessary steps to address this situation responsibly."

Six vehicles were involved in the crash shortly before 6:30 p.m. Saturday in the northbound lanes of North Central Expressway, Dallas police said.

The people in the Lamborghini and Corvette left the scene without determining if anyone needed medical attention or providing their information, police said. Two of the drivers in the other vehicles were treated at the scene for minor injuries, and two occupants of another vehicle were taken to a hospital with minor injuries.
