The Islanders sorely miss veteran defender Lubomir Visnovsky. Last year, Visnovsky was signed seemingly to take the place of Mark Streit as a top-four defender and point man on the team's power play. But that hasn't gone according to plan.The Slovakian defender hasn't been seen on the ice since he suffered a concussion against the Hurricanes on October 19th of this season, playing in only eight games. To this point, Visnovsky has still not been cleared for on-ice workouts.In today's Newsday, Arthur Staple reports that while there has been little progress on Visnovsky, his camp hasn't discussed shutting things down for the season. Staple notes that while Visnovsky could resume skating soon, the timetable for a return to game action is anything but:[sny-box]Visnovsky may take another baseline neurological exam next week, according to a source; if he passes that, he could resume skating soon after.Best-case scenario: He returns to play a game or two before the Olympic break. Next-best case: He's back right after the break. Beyond that, it's not a scenario the Islanders want to envision.[/sny-box]The best case scenario for Visnovsky is still a month away and the worst case, well, it's anyone's guess how for away the worst case scenario takes it.
