The coach's challenge went in the Chicago Blackhawks' favor multiple times in Game 2 against the St. Louis Blues.
Andrew Shaw scored a power-play goal to give the Blackhawks a 2-1 lead with 4:19 remaining Friday night. The call was confirmed upon review by the officials, then challenged by the Blues for goaltender interference before eventually being upheld.
Shaw's goal came minutes after Vladimir Tarasenko's goal was disallowed because teammate Jori Lehtera was deemed offside.
