Koivu is unavailable due to the league's COVID-19 protocols.
It was reported earlier Wednesday that Koivu was set to miss Thursday's game against Nashville, and he's now had that absence clarified. It's unclear when Koivu will gain clearance, but he won't be able to practice or travel with the team for now. Expect Riley Nash to center the fourth line with Alexandre Texier taking over the third-line center spot.
