"(The) Pens are optimistic that it may not be too long (for Murray to return), but in the meantime, the Pens will not be looking externally for any help," TSN's Bob McKenzie said on Tuesday's edition of "Insider Trading."
"Casey DeSmith is scheduled to be the starter against the Vegas Golden Knights on Thursday night. Tristan Jarry is coming back off (an) injury, DeSmith is ready to play, but for the foreseeable future, as long as Murray is out of the lineup, it's expected to be DeSmith and Jarry."
The Penguins revealed Tuesday that Murray sustained a concussion in Monday's practice.
It's his second in about eight months. He also suffered one in practice back in February.
