Update, 9:10pm: The Islanders have announced that Visnovsky suffered a concussion. The Islanders defense and power play could be in trouble, as Lubomir Visnovsky left tonight's game against Carolina during the first period and did not return. He was injured on a hit from #20 Riley Nash that looks clean. Visnovsky made it to the bench on his own and left the ice during the ensuing TV timeout with the help of a trainer and Travis Hamonic. While leaving the ice, he was hunched over and it appeared as though he was favoring one of his arms.
