The Toronto Maple Leafs hit the ice for morning skate and after Jack Campbell, the team was accompanied by a different goalie. 

That's because Petr Mrazek seems to be sidelined again. 

Joseph Woll was on the ice as the second goalie during practice and head coach Sheldon Keefe revealed why after practice. 

Mrazek returned from his groin injury last week but Keefe revealed that the goalie tweeked it and is now being evaluated. 

The injury forced the goalie to miss 6 games earlier this season and it's likely he misses more time. 

Keefe told reporters we'd know more about the injury tomorrow.
