Clint Benson, 21, was driving erratically in the parking lot of a New Jersey bar shortly after midnight March 17 -- St. Patrick's Day -- when he struck Richard Lachner, 23. The New York Post said Sunday Lachner suffered a fractured skull and bruised lungs. He has since been released from the hospital.
The younger Benson allegedly left the scene, then returned before leaving again and crashing his car into a guard rail nearby, police said. His blood alcohol content was measured at 0.20 percent following a breath test, police said He was charged with driving under the influence and aggravated assault.
The elder Benson played 10 seasons for the Giants from 1978-88. Since retiring he's opened a car dealership in northern New Jersey and has become known for his loudmouth commercials selling Hyundais, the Post said.
His son was driving a Nissan during the incident, the Post said.
