Lehtera has two assists in the series, playing on a line with top scorer Vladimir Tarasenko, and is a key member of the power play. He was injured in the third period of Game 4 absorbing a shot by teammate Jay Bouwmeester.
Marcel Goc replaced Lehtera in the lineup. Goc was a healthy scratch in Game 4, a 6-1 rout in Minnesota, after playing the first three games on the checking line.
The series was tied at two games apiece.
