Oleksiak (illness) is not in Thursday's lineup versus the Sharks, Marisa Ingemi of The Seattle Times reports.
Oleksiak was deemed doubtful to play Thursday, and he won't suit up for the contest. The 29-year-old's next chance to return is Friday versus the Blues. Will Borgen and Jeremy Lauzon will handle third-pairing minutes Thursday while Carson Soucy moves into the top four.
