Tarasenko (undisclosed) was not on the ice for warmups and is expected to miss Sunday's contest against the Canucks, Elliotte Friedman of Sportsnet reports.

EDGE Analysis

It's unclear why Tarasenko won't suit up Monday, but it's obviously a huge blow to the Blues who are already facing a 2-0 series deficit. For now, he'll be considered questionable for Game 4 on Monday.
