The Edmonton Oilers are dealing with a potentially serious early-season injury.

Ahead of Saturday's game against Ottawa, head coach Todd McLellan disclosed forward Leon Draisaitl is dealing with concussion-type symptoms.

Draisaitl missed practice the past few days after suffering en eye injury during the team's loss Monday against Winnipeg, a game in which he played over 18 minutes, and scored a goal.

"He’s had an eye injury and the eye was swollen shut but obviously the eye is attached to the head which leads to concussion-type symptoms,” McLellan said per Jim Matheson of the Edmonton Journal.

He will therefore not play against the Senators and will be held out of the lineup until deemed clear of the concussion symptoms.

Draisaitl, who signed an eight-year, $68 million extension this past summer, recorded a goal and two assists in three games so far this season.
