Boston Bruins goaltender Tuukka Rask left Saturday's game against the New York Rangers 10 seconds into the middle frame for what coach Claude Julien referred to afterwards as a possible case of dehydration. 

Rask skated over to the bench, spoke with Julien and headed down the runway to the dressing room.

He was replaced by backup Niklas Svedberg with the Bruins ahead 3-0 in an eventual 4-2 victory. 

Julien indicated that Rask is scheduled to travel with the team and should be fine. 

"We just found out at the beginning of the second [period]", said Julien, I said, 'Are you still having those symptoms?' He said, 'Yep.' So I said, 'Let's get you out of here."'

In need of a backup goalie for the remainder of the game, the Bruins decided to call upon the team's goalie coach, 50-year-old Bob Essensa. 

Essensa, who played 12 NHL seasons and retired in 2002, was not called into action, but, nonetheless, he appeared to take the assignment quite seriously.
