Perron was skating along the boards in the offensive zone when he took a shoulder hit from Blackhawks defenseman Jake McCabe with 8:06 left in the first period. The impact of the hit drove Perron into the glass, but he skated off on his own to the bench before heading to the locker room.
After the game, Blues Head Coach Craig Berube said there wasn't an update on Perron's injury status.
Through 19 games this season, Perron has seven goals and 11 assists (18 points).
