The Toronto Maple Leafs could be without Morgan Rielly for at least the next three games, as the defenseman was placed on the injured reserve Monday.

Rielly missed Saturday's contest against the rival Ottawa Senators, and he'll also be sidelined for upcoming contests against Colorado, Chicago, and Dallas. The three games will be followed by a five-day break for the All-Star Game.

Players must remain on the injured reserve for a minimum of seven days, meaning Rielly could return as soon as Jan. 31, versus the New York Islanders.

It's a key loss for the Maple Leafs, as the team relies on Rielly for more than 22 minutes a game. Through 47 games, he has five goals and 26 assists.

In Rielly's place, blue-liner Rinat Valiev has been recalled from the AHL's Toronto Marlies.
