New York Islanders
defenseman Mark Streit
left Saturday's scrimmage in the third period with an injured left shoulder.
Streit, the Isles' top defenseman, was injured in a collision with Matt Moulson
near the bench. He immediately went to the locker room and did not return. After the scrimmage, he had a sling on his left arm.
Isles coach Scott Gordon
said the team won't know the extent of the injury for a while, possibly not until Sunday or Monday.
"That was a pretty flukish … he kind of couldn't get out of his own way more than anything else," Gordon said. "He got himself jammed up against the boards."
Losing Streit for any length of time would be damaging to the Isles. Streit sees more ice time than anyone on the team, runs the power play and plays on the penalty kill.
"He's an important guy for us," Gordon said. "Any team that would lose one of its top defensemen would have a hole in the lineup."
The Isles don't play their first preseason game until Wednesday night. They open the season Oct. 8 against Dallas.
