Klingberg signed a one-year, $4.15 million contract with the Maple Leafs on July 1, 2023, after playing the 2022-23 season with the Anaheim Ducks and Minnesota Wild. The defenseman played 14 games with Toronto — scoring four assists and averaging 20:33 of ice time — before undergoing hip surgery.

The Toronto Maple Leafs have been dealt a significant blow with John Tavares landing on injured reserve due to a lower-body injury sustained in practice, but they have already make a subsequent roster move to make up for his absence.

Toronto will be without one of its biggest contributors for the near future after a drill mishap on Wednesday.
