Visnovsky has been ruled out indefinitely with a suspected concussion, Newsday's Arthur Staple reports. Visnovsky was already ruled out for Thursday's Game 5 against the Capitals after failing to return to the ice for morning skate, and now it appears safe to rule him out for the remainder of the series, if not beyond. The blueliner missed 58 games last season with a concussion, and appeared to suffer another head injury that sidelined him briefly in Game 3 before the hit he took from Tom Wilson in Game 4 knocked him out for good. The 38-year-old will be a free agent after the season, and if he fails to return before the Isles' playoff run ends, it's possible his career could be over.
