Kassian has been placed in the league's COVID-19 protocols, according to Daniel Nugent-Bowman of The Athletic.
EDGE Analysis
Kassian has just four goals and eight assists across 25 appearances for the Oilers, but the 30-year-old winger is still one of the team's most important players and his absence will be greatly felt. Kailer Yamamoto could be in line to see extra time on the ice as his potential replacement.
