The New York Islanders said Sunday their top defenceman, Mark Streit, will be out of the lineup indefinitely.
Streit, 32, crashed into the boards during a scrimmage Saturday and suffered a left shoulder injury.
Streit has averaged 14 goals and 39 assists over his first two seasons with the Islanders, serving as a power-play specialist.
Before that, the native of Bern, Switzerland, spent parts of three seasons with the Montreal Canadiens, during which he played forward and defence.
Streit is scheduled to make $4.1 million US this NHL season, the third in a five-year deal with the Islanders.
The Islanders signed veteran defenceman Anders Eriksson to a pro tryout on the weekend, as well as forward Dean McAmmond and goalie Manny Legace.
