Graovac, 22, played just under 14 minutes in Minnesota’s crazy 5-4 comeback win over Colorado in the season-opener, but sat out Saturday’s win over St. Louis.
At 6-foot-5 and 200 pounds, Graovac was a notable physical presence in the Wild lineup, and is an intriguing prospect — he impressed with AHL Iowa last year, scoring 21 goals and 46 points in 73 games.
Hall did not skate with the Oilers this morning. If he can’t play, Edmonton’s top two lines against the Stars could feature Ryan Nugent-Hopkins between wingers Teddy Purcell and Benoit Pouliot, followed by Connor McDavid centering Lauri Korpikoski and Nail Yakupov.
The Oilers — forced to start the season without top-six winger Jordan Eberle — have scored just once in their first two games, losing 3-1 in St. Louis and 2-0 in Nashville.
Edmonton returns home after tonight’s contest to play St. Louis on Thursday. Then it’s back out on the road for games against Calgary and Vancouver.
