Marner has made the Maple Leafs' Opening Night roster, Terry Koshan of the Toronto Sun reports.

EDGE Analysis

The 19-year-old impressed the Leafs' brass all camp long and will officially make his NHL debut Wednesday at the tender age of 19. Marner, the fourth-overall pick in 2015, is coming off two insanely productive seasons with the London Knights of the OHL that saw him pile up a whopping 242 points in just 120 games. He'll look to make an immediate impact on the second line with James van Riemsdyk and Tyler Bozak, a pair of established NHLers that Marner is likely to man a power-play unit with, as well.
