Mason left Saturday's game at the 3:16 point of the third period after appearing to injure himself when the Leafs scored their third goal.

EDGE Analysis

He was seen at the bench getting assistance with his right knee, which he seemed to grab after a minor collision with the Leafs' Nazem Kadri. Mason seemed to be fine soon after, but was not put back in the game. He did spend considerable time re-hydrating, so perhaps it was more illness related than anything else.
