Smith (back) was placed on injured reserve Tuesday.
Smith was waived by the Blackhawks on Jan. 4 and evidently still hasn't fully recovered from the back surgery he underwent in February. The 32-year-old pivot has just one year remaining on the four-year, $13 million contract he signed with Ottawa in 2017, and at this point it isn't clear if he'll be healthy enough to play in 2020-21.
