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 Wild made one lineup tweak, inserting forward Matt Cooke and scratching Sean Bergenheim.
The series was tied at two games apiece.
