Bruins' Rick Nash dealing with concussion

Rick Nash has revealed the true nature of his injury, as the Boston Bruins forward informed the media he has been sidelined with a concussion that forced him to miss the past 10 games.

The team previously described Nash's ailment as an upper-body injury.

Nash skated Saturday but won't play against the Ottawa Senators. The possibility remains he could dress for Sunday's season finale versus the Florida Panthers. The veteran forward is optimistic he'll be ready to return for the opening round of the postseason.

The Bruins acquired Nash from the New York Rangers at this year's trade deadline, and paid a heavy price to do so, parting with first- and seventh-round picks, forwards Ryan Spooner and Matt Beleskey, and defenseman Ryan Lindgren.

Nash has suited up for 11 games with the Bruins, in which he has potted three goals and three assists. His last appearance came March 17.
