Draisaitl was injured a week ago against the Jets and sat out practice last week.
Draisaitl has been skating on a line with star Connor McDavid. He has a goal and two assists this season after signing an eight-year, $68 million contract during the offseason.
The 22-year-old Draisaitl had 29 goals and 48 assists for 77 points last season.
After winning their opener, the Oilers, who are favorites in the West this season, have lost three straight.
