The Pens have recalled Filip Hallander from the American Hockey League.
The announcement of the recall, which was made on an emergency basis, was released Monday afternoon.
The recall of Hallander comes at a time when the Penguins could find themselves a few players short.
It's unclear whether their status will be affected by the illness, or even if the illness could spread further through the team.
So far this season, Hallander has played in 52 games for the WBS Penguins in the AHL.
