Grubauer (lower body) and defenseman Justin Schultz (upper body) both left Saturday night's 4-3 overtime loss to the Tampa Bay Lightning. The goalie stopped 21 of 23 shots before exiting and did not factor into the decision.
Grubauer, in net for Seattle's previous two December games, both losses, is 5-9-1 this season with a 3.25 goals-against average and an .884 save percentage.
To fill roster space, Seattle recalled goaltender Chris Driedger and defenseman Jaycob Megna from the American Hockey League. But it was Joey Daccord, Grubauer's traditional backup, who started on Sunday night, taking the loss in a 2-0 decision at the hands of the Minnesota Wild.
Driedger hasn't played with the Kraken since the 2021-22 season, Seattle's first in the NHL. He went 9-14-1 with a 2.96 GAA and an .899 save percentage that season.
Seattle, a playoff team last year, is struggling in its third season. With Sunday's loss, the Kraken are 8-14-7 with just 23 points, five away from the Western Conferenece's final wild-card berth.
