Dunn (upper body) will be a game-time decision Tuesday versus Nashville, according to Kate Shefte of The Seattle Times.
Dunn participated in Tuesday's morning skate after sitting out Saturday's 5-4 shootout win over Minnesota. He has collected one goal, one assist, six shots on net and six blocked shots through two contests this campaign. If Dunn returns to the lineup versus the Predators, Josh Mahura will likely be a healthy scratch.
