Reaves was given a five-minute major and a game-misconduct in the first period after the hit. The Blackhawks scored a power-play goal on the ensuing penalty to take a 1-0 lead.
"You could probably see I disagreed with the call yesterday. I think the League did, too," Reaves said after Thursday's practice at Scottrade Center. "There's no discipline and they took away the 10 (minutes) on my record."
The Blues overcame the penalty, eventually earning a 3-2 shootout victory at Scottrade Center.
