Maple Leafs' Semyon Der-Arguchintsev: Day-to-day with undisclosed injury

Der-Arguchintsev will miss Wednesday's preseason matchup with Ottawa due to an undisclosed injury, David Alter of The Hockey News reports.

Der-Arguchintsev split time between the KHL and AHL last year in which he tallied 10 points in a combined 23 contests. The 21-year-old center will be hard-pressed to break into the Opening Night roster even without the injury and figures to start the year in the minors.
