McDavid missed the club's last six games with a quad injury.
"A little boost like that would be good for us right now," said head coach Dave Tippett, according to NHL.com's Dan Greenspan. "When you can add a player like that to your lineup, it just gives another whole dimension to our team."
The 23-year-old ranks second on the Oilers in both goals (30) and points (81) through 55 games this season.
With Leon Draisaitl leading the way while tallying four goals and 12 points, the Oilers posted a 3-2-1 record in McDavid's absence.
