The Toronto Maple Leafs get a nice boost tonight when they hit the ice against the Ottawa Senators. 

Forward Joe Thornton plays for the first time since missing almost a month of action and he'll reclaim his spot on the top line beside Auston Matthews and Mitch Marner. 

What does that mean for Zach Hyman and the rest of the lineup?

Head coach Sheldon Keefe confirmed the rest of tonight's lineup.

Hyman will drop down to the second line and skate beside John Tavares and William Nylander while Ilya Mikheyev will roll with Alexander Kerfoot and Pierre Engvall. 

Jimmy Vesey will find himself on the fourth line with Travis Boyd and Jason Spezza.
