TORONTO - Former NHL player Rob Ramage began serving a four-year prison sentence Monday.

Ramage lost a bid for a new trial on impaired driving charges in a car crash that killed another ex-NHL player.

Ramage was convicted in 2007 of four charges including impaired driving causing death in the crash that killed his friend Keith Magnuson.

Ramage also received a five-year driving ban.

The decision rejecting the appeal was filed by the Ontario Court of Appeal last Friday and Ramage surrendered to police today.

Lawyer Brian Greenspan says Ramage isn't planning to appeal the decision.

Greenspan says efforts will be made to have Ramage released to a halfway house as soon as possible.

Magnuson died when a rental car driven by Ramage slammed head-on into another vehicle north of Toronto in December 2003.

The two men had just left a funeral reception for another former N-H-L player, Keith McCreary.
