The Maple Leafs, who had acquired Dzingel as part of a deal with the Arizona Coyotes on Saturday, intended to assign Dzingel to the AHL's Toronto Marlies, where he would provide further depth for the franchise.
"He's an NHL player and selfishly we hope he [clears waivers] and hope he provides depth," Maple Leafs general manager Kyle Dubas said after the trade. "If not, that will just be another contract and some cash for us."
Dzingel is in the final year of a contract that carries a cap hit of $1.1 million. The 29-year-old is a seven-season NHL veteran who was first drafted by the Ottawa Senators in the seventh round of the 2011 draft. He went on to play three-and-a-half seasons in Ottawa before being traded to the Columbus Blue Jackets.
He has since had stints with the Carolina Hurricanes and he made a return to the Senators before he signed this past summer with Arizona.
In 26 games played this season, Dzingel has seven points and 35 penalty minutes.
