Atlanta ? Atlanta Thrashers forward Dan Snyder died Sunday night, six days after he was involved in a horrific car crash with teammate Dany Heatley.

Snyder died at Grady Hospital from massive brain injuries without ever regaining consciousness, the team said. He was 25.

Police said Heatley was driving his Ferrari at about 80 mph on a narrow two-lane road Monday night when he lost control, spun off the road and smashed into a brick and wrought-iron fence.

The car split in half. The players were thrown into the road. Heatley already was facing several charges, including a felony.

“The charges will be upgraded. It hasn’t occurred yet,” Sgt. John Quigley, an Atlanta Police Department spokesman, said Sunday night. “I expect them to be upgraded in the near future.”

He said investigators would meet with the District Attorney’s office this morning.

“It would likely be vehicular homicide first degree,” Quigley said.

That charge carries a prison sentence of three to 15 years. A plea bargain to the lesser charge of second-degree vehicular homicide, a misdemeanor, is also possible.

Snyder underwent surgery for a skull fracture, but never emerged from his coma.

“We are deeply saddened by the tragic loss of Dan Snyder,” the Thrashers said in a statement. “Dan was a teammate and friend to all of us. We feel a tremendous amount of pain as an organization and extend deepest sympathies to his family.”

Snyder, a center who had 10 goals and four assists in 36 games for Atlanta last season, was expected to start the season on the injured list.
