Walman (undisclosed) won't play Wednesday versus the Blues, Oilers play-by-play announcer Jack Michaels reports.

EDGE Analysis

While the Oilers will get a full complement of forwards in Connor McDavid's return from a lower-body injury, they'll be forced to play short on defense. It's unclear when Walman sustained the injury, as he had an assist and played 23:23 in Monday's loss to the Ducks.
