Mrazek will start on the road versus the Oilers on Saturday, Ben Pope of the Chicago Sun-Times reports.
Mrazek allowed four goals on 24 shots to Utah in his first outing of the season. He was on the bench for Friday's 2-1 overtime loss to the Jets, which was a start for Arvid Soderblom. Mrazek will be tested against one of the league's projected top offenses, though the Oilers were shut out in their season opener Wednesday against the Jets.
