Oilers forward Taylor Hall will be out 2-to-4 weeks because of an injured left shoulder.
The Oilers made the announcement Monday night after a 2-1 home loss to the Nashville Predators. Hall had an MRI exam earlier Monday.
The 20-year-old Hall, in his second NHL season after being chosen No. 1 overall by Edmonton in the 2010 draft, was injured during a 5-2 loss to Colorado on Saturday after a crushing hit into the boards.
Hall dropped his stick and immediately went to the bench for treatment. He made a brief return to the game, but was unable to finish it.
In 22 games this season with Edmonton, the left wing has seven goals and 18 assists.
