The 26-year-old knocked Czarnik out of a pre-season game on Saturday and was assessed a minor penalty for boarding. Czarnik has been diagnosed with a concussion.
This is the second suspension of Gudas’ career.
He was given a three-game ban for an illegal chack to the head of Mika Zibanejad last season.
Gudas will forfeit just over $245,000 in salary while suspended. The money goes to the Players' Emergency Assistance Fund.
