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.
I've never seen anything like that. The great thing is I don't know how many times guys bailed me out where they had to score to keep it alive and they did every time. It was amazing. It's not the way we draw it up, to go 20 rounds here, but obviously it's a big win.
