The team said a time frame for Boychuk's return would be determined when he meets with the team's doctors next week.
The Islanders recalled defenseman Adam Pelech from their AHL affiliate in Connecticut, the Bridgeport Sound Tigers, in a corresponding move.
"It looked like he just caught an edge-type thing and went in hard and he's a big guy,'' Islanders coach Jack Capuano said after the game. "Fortunate that it wasn't his head or his neck and that's the most important thing.''
The 31-year-old Boychuk has three goals and 11 assists this season.
