Polak hit Bjorkstrand from behind early in the third period of the Maple Leafs' victory in Columbus on Wednesday night. The NHL department of player safety announced the suspension Thursday.
Polak was given a five-minute major for boarding and a game misconduct on the play. He will forfeit $25,000 in salary as a result of his first career suspension.
Bjorkstrand did not return to the game, and his status for the Blue Jackets' game Thursday night in Washington was not clear.
Polak has four goals and four assists and 61 penalty minutes in 67 games this season. The Maple Leafs face the New Jersey Devils on Thursday night.
