Kadri confirmed the suspension at Toronto's practice Wednesday. The hit occurred in the Oilers' 4-1 home victory over Toronto on Monday.
"I'm not happy about it, but what are you going to do at this point?" said Kadri, who will forfeit $141,463 in salary. "Obviously it wasn't my intent to injure the player and I hope he's doing all right."
Kadri skated by Fraser behind Toronto's net and hit the Oilers forward in the head with his left shoulder. Fraser left the game, and Kadri was given a two-minute minor penalty.
The hit occurred in Kadri's second game back after a team-issued, three-game suspension for off-ice behavior.
The Leafs play at home Thursday against the San Jose Sharks.
