According to a report by Arthur Staple of Newsday, Visnovsky also will miss Thursday's game against the New York Rangers.
Visnovsky has a goal and six points in 12 games since joining the Islanders.
He initially was suspended by the team at the beginning of the season for failure to report following a trade from the Anaheim Ducks. Visnovsky's agent later said he was tending to personal matters and reported to the Islanders last month, making his season debut Feb. 9.
We never really stopped believing in ourselves. We were hearing a lot of things about our team in the regular season. Seems like we put things back together at the right time and we're back in the finals with this group. We know what we have in this room, we believe in each other, we believe in the organization and it really matter what other people say.
