Luukkonen (undisclosed) won't start in Saturday's road matchup against Philadelphia, Lance Lysowski of The Buffalo News reports.
Luukkonen has been dealing with an undisclosed injury and is considered day-to-day, and he'll be unavailable for a second consecutive game Saturday. He's been skating in recent days, but it's not yet clear whether he'll be in the mix to return for Wednesday's game against Los Angeles.
