Grubauer gave up three goals on 26 shots in Friday's 3-0 loss to the Lightning.
After taking down the Capitals and the Hurricanes, Grubauer received no support against the Lightning. The German netminder dropped to 6-9-1 with a 3.03 GAA and an .890 save percentage in 17 games. He's started six of the last seven contests, but Chris Driedger will likely draw a tough matchup versus the Panthers on Saturday.
