Mitchell was recalled along with Mason Lohrei and Parker Wotherspoon to aid a Bruins' blueline that is currently without Charlie McAvoy (suspension) and Matt Grzelcyk (upper body). Mitchell was the 57th overall pick of the Chicago Blackhawks in the 2017 NHL Entry Draft and already had a two-game stint with the Bruins earlier this season, recording one point (0G / 1A) and four penalty minutes.
