The Calgary Flames defenseman is facing discipline for an illegal check to the head against Dallas Stars forward Luke Glendening.
The incident occurred at 3:50 of the second period in the Flames' 4-2 loss in Game 6 of the Western Conference First Round at American Airlines Center on Friday. No penalty was assessed on the play.
Glendening left the game and did not return.
Game 7 of the series will be at Calgary on Sunday (9:30 p.m. ET; ESPN2, SN, TVAS, BSSW).
The following grounds are being considered for supplemental discipline: illegal check to the head. However, the Department of Player Safety retains the right to make adjustments to the infraction upon review.
