Bruins general manager Peter Chiarelli says he was preparing for disappointment before his team pulled off its remarkable comeback.

He says he was thinking ahead to what the next few days would be like until Boston started its third-period rally and beat the Toronto Maple Leafs 5-4 in overtime of Game 7 of an NHL first-round series Monday night.

The Bruins became the first team to win a playoff game after trailing by three goals in the third period.

Now they face the New York Rangers in the Eastern Conference semifinals starting Thursday night in Boston.

Chiarelli said he had no update on injuries to veteran defensemen. Andrew Ference and Wade Redden missed Game 7 and Dennis Seidenberg played just 37 seconds before leaving with a left leg injury.
