Kadri received a two-minute minor penalty for the hit, which happened during Monday's 4-1 loss in Edmonton.
Fraser was helped off the ice and did not return to the game. He was diagnosed with a concussion.
Kadri is a repeat offender under league rules, as he was suspended three games last season for a hit to the head of Minnesota Wild goaltender Niklas Backstrom.
Kadri was playing in his second game since returning from a team-issued three-game hiatus for off-ice behaviour.
