Miller (undisclosed) took line rushes and is expected to play Wednesday versus the Penguins, Brendan Batchelor of Sportsnet 650 reports.
Miller was considered questionable after taking a maintenance day Tuesday, but it appears he's good to go. The 28-year-old will likely exceed 20 minutes of ice time as he looks to sustain a point-per-game pace this year (seven goals, 12 helpers in 19 games).
