Marchenko may not be available versus the Canadiens on Tuesday while awaiting a work visa, Chris Johnston of The Athletic reports.
With the Leafs' kicking off the season with a back-to-back, it's possible Marchenko is forced to miss the first two games of the year while resolving his work visa. Whenever the 26-year-old winger does link up with the Leafs, he should slot into both a top-six role and a spot on the No. 1 power-play unit.
