McDavid has missed seven games this season. He was sidelined for three games from Oct. 31 to Nov. 4 with an ankle injury and was suspended three games for cross-checking Vancouver Canucks winger Conor Garland in January.

The Edmonton Oilers host the Dallas Stars on Wednesday night in a massive game. Both teams are entrenched in the playoffs but are battling for seeding before what should be a contentious first round.

It is uncertain when exactly McDavid was injured; he had six shifts in the second period against Winnipeg, with his final shift lasting 18 seconds before returning to the bench at 19:03. McDavid spoke with Oilers head athletic therapist T.D. Forss on the bench before the end of the period and did not return for the third.
