Lehtonen allowed five goals on 24 shots in Sunday's 6-3 loss against the Lightning.
Lehtonen was rolling right along with a 1.32 GAA, .950 save percentage and a pair of shutouts over his previous six starts, so this was a disappointing showing, to say the least. The Stars face the Coyotes in Dallas on Tuesday, so look for Lehtonen to bounce back if he is tabbed for that favorable matchup.
