Mason says he won't dress for the game and his status for the series remains iffy because of an upper-body injury. Mason shared practice time with Emery on Monday.
Emery was excellent in Sunday's 4-2 comeback win at Madison Square Garden that tied the best-of-seven, first-round series at 1-1.
Emery made 31 saves in Game 2 to win his first post-season game anywhere in exactly three years for Anaheim at Nashville. Mason hasn't played since he was injured in a collision in the next-to-last game of the regular season on April 12.
For our team, as a group, we've never been this far before, and so it's just more lessons learned, and sometimes you have to go to the school of hard knocks to find out what works and what doesn't. We've got a young group. They've played some unreal hockey here to get us this far, and we showed if we're not going to play the proper way, a really, really good hockey team is going to beat you, and that's what they did. It's a lesson learned.
