Horton/By S. Bradley

WILMINGTON, Mass. — The Bruins confirmed two things today at Ristuccia Arena that most expected even before the team took the ice for practice.

First, general manager Peter Chiarelli confirmed that forward Nathan Horton will not return during the 2012 Stanley Cup Playoffs. Horton has been out with a concussion since Jan. 22.

Horton has missed 36 games and he has hit several roadblocks in his attempt to return to the lineup. For more, check my NHL.com story.

•After his team’s final practice in preparation for Game 1 of the Eastern Conference Quarterfinals with Washington Thursday night, head coach Claude Julien said that defenseman Adam McQuaid would not be available against the Capitals. McQuaid hasn’t skated since leaving the game in Ottawa April 5 with an upper-body injury.

Julien also said a decision would be made on Johnny Boychuk Thursday and that Tuukka Rask would not be available unless the medical staff tells the coach differently Thursday. Both Rask and Boychuk practiced three straight days this week.
