Nathan Horton, who has been sidelined since Jan. 22, has been ruled out for the entire Stanley Cup playoffs because of a concussion. "In his case, it's probably the best thing for, No. 1, him," coach Claude Julien said. "As an organization, you've got to make the right decision. He's tried to come back a few times. He's had some setbacks lately. You could tell he was feeling the pressure of trying to come back for the playoffs. When you're not feeling well, that's not right. It was important for us to let him know we're going to shut him down for the rest of the year." Boston GM Peter Chiarelli is expecting Horton to be ready for next season.
