Montreal Canadiens forward Jonathan Drouin is day-to-day with an upper-body injury and will be held out of Monday’s pre-season game against the Toronto Maple Leafs as a result.

Drouin is Montreal’s prized off-season addition, coming over from Tampa Bay in exchange for prospect Mikhail Sergachev.

He signed a six-year, $33-million contract with the Canadiens after a year in which the 22-year-old scored 21 goals and 53 points in 73 games.

Torrey Mitchell will replace Drouin in the Canadiens lineup for Monday’s game at Ricoh Coliseum.
