Dumba (lower body) is set to undergo imaging and will be re-evaluated Monday, effectively ruling him out for Sunday's game versus the Kraken, Sam Nestler of DLLS Stars reports.
Dumba was injured in the first period of Saturday's game against the Islanders. With the 30-year-old defenseman out of action Sunday, look for Brendan Smith to take on a third-pairing role, while Thomas Harley could jump onto the first pairing alongside Miro Heiskanen.
