The defending Stanley Cup champions were on the ropes, but rallied for a needed victory.
The Blues had the Blackhawks reeling after Vladimir Tarasenko scored what appeared to be his second goal of the game Friday night. The tally was waved off after Chicago successfully challenged that the Blues were offside on the play.
The controversial replay review wiped out what would have been a Blues go-ahead goal. Less than four minutes later, Andrew Shaw's tip-in rebound gave the Blackhawks a 2-1 lead with 4:19 remaining.
