KILN, Miss. (AP) – Green Bay Packers quarterback Brett Favre’s father died Sunday of a heart attack or a stroke while he was driving, Mississippi state police said. Irvin Favre was 58.

Favre went off the road at 5:23 p.m. near Kiln, the hometown of Brett, a three-time NFL most valuable player.

Irvin Favre ran into a ditch, said Sgt. Joe Gazzo of the Mississippi State Highway Patrol.

“It didn’t appear that the accident was serious enough to cause him to be unconscious, so that leads us to believe that a medical condition was what caused him to go off the road,” Gazzo said.

Irvin Favre was pronounced dead at 6:15 p.m.

An autopsy will be performed Monday.

“First, the witnesses, then the ambulance, and then at the hospital they tried to revive him,” Gazzo said.

“It’s going to be a great loss to the community, he was a great guy.”
