Ellis (undisclosed) will miss Saturday's road game against Toronto, per Elliotte Friedman of Sportsnet.
Ellis was originally going to start Saturday, according to Friedman, but he's not 100 percent. Ukko-Pekka Luukkonen (lower body) will make his season debut instead after being activated off injured reserve Thursday. Ellis won his NHL debut Wednesday, stopping 29 of 31 shots against Detroit.
