No supplemental discipline will be levied against the Toronto Maple Leafs forward for checking the Philadelphia Flyers defenseman in the numbers from behind Saturday night, according to the Courier-Post's Dave Isaac.
Komarov drove Gostisbehere headfirst into the glass midway through the second period of the Flyers' 4-2 victory over the Maple Leafs.
No penalty was assessed on the play.
Gostisbehere initially stayed in the game and assisted on Valtteri Filppula's decisive goal, but the blue-liner didn't emerge for the third period.
After the game, Flyers head coach Dave Hakstol implored the Department of Player Safety to review the hit, according to Isaac.
Komarov didn't appear to believe he did anything wrong.
Gostisbehere leads all NHL defensemen with 12 assists and 13 points in 11 games.
