UNIONDALE, N.Y. -- The New York Islanders won 6-4 against the Pittsburgh Penguins on Tuesday night but lost key defenseman Andrew MacDonald in tying the series 2-2.
According to Newsday, MacDonald suffered a broken hand during the second period of Game 4 after he was hit by a shot from Penguins defenseman Douglas Murray on the arm and is unlikely to return during the playoffs.
MacDonald did not return to the ice after the play, forcing the Isles to roll five defensemen the rest of the game.
The 25-year-old MacDonald, who plays with Travis Hamonic on the team's top defensive pairing, leads the Islanders with 23:31 minutes of ice time per game.
"He's an integral part of our team, no question," Islanders coach Jack Capuano said after the game.
Capuano said he thinks that others will be able to step up in MacDonald's absence. Assuming MacDonald misses Game 5, the Islanders will likely use veteran Radek Martinek, a scratch the first four games of the series.
