The Toronto Maple Leafs hit the ice for practice today as they prepare to take on the Flyers on Tuesday in Philly. 

We saw some interesting changes at practice today which started with the return of Mitch Marner at practice. 

Marner was full go at practice and skated on a line with John Tavares and Ilya Mikheyev.

What made practice even more interesting was the change on the power play that head coach Sheldon Keefe introduced because of Marner's return. 

Morgan Rielly was booted off the first power play unit in favour of Marner and Tyson Barrie took over as the first power play unit's only defenseman. 

Zach Hyman was also back at practice and skated alongside Alexander Kerfoot and Kasperi Kapanen on the team's third line. 

Here's a look at the lines from practice and power play units:
