What happened: Forward Rutger McGroarty and defenseman Chase Pietila move up from @WBSPenguins in the AHL while forwards Ben Kindel and Bryan Rust go on injured reserve.

Why it matters: The transaction reverses McGroarty's earlier assignment to @WBSPenguins to replenish forward depth alongside blue-line coverage from Pietila.

What to watch: Pittsburgh and the Florida Panthers are scheduled to meet with the updated active roster in place.
