Calgary Flames defenseman Nikita Zadorov will not receive supplemental discipline from the NHL for his hit on Dallas Stars forward Luke Glendening, the league announced Saturday.

The hearing followed Zadorov's illegal check to the head of Glendening in the Flames' Game 6 loss on Friday. No penalty was assessed on the play.

Glendening left the game and didn't return following the incident, which occurred at 3:50 of the second period of the game in Dallas.

"After thoroughly reviewing all available video and following a telephone hearing today, the Department of Player Safety has determined that there will be no supplemental discipline assessed to Calgary's Nikita Zadorov for his hit against Dallas' Luke Glendening," the NHL Player Safety wrote on its Twitter account.

"While there was significant head contact on this play, Zadorov took a proper angle of approach, did not extend outward or upward, and hit through Glendening's core. Therefore, under Rule 48.1 (i), the head contact was determined to be unavoidable."

The series is tied at three games apiece. The deciding Game 7 is scheduled for Sunday night in Calgary.

Zadorov, 27, recorded had 22 points (four goals, 18 assists) in 74 games this season. He has two assists in the six games of the playoff series.

Glendening, 33, had 16 points (nine goals, seven assists) and skated in all 82 games this season. He has not scored in this series.
