Yeo's firing doesn't come as much of a surprise considering the Blues' struggles so far this season. After coming into the season with a revamped roster and high expectations, St. Louis struggled out of the gate and have limped to a 7-8-3 record through 18 games, putting it in last place in the Central Division.
Yeo, who took over for Ken Hitchcock behind the Blues bench in 2017, had a 73-48-11 record over parts of three seasons in St. Louis.
Monday's firing came after the Blues lost 2-0 to the Kings at home, making it four losses in their past five games. Three of those losses have come via shutout.
Berube, who spent 17 seasons in the NHL as a player, has limited NHL head coaching experience. He served as head coach of the Philadelphia Flyers from 2013 to '15, posting a 75-58-28 record during his tenure. He also coached the AHL's Chicago Wolves to a first-place finish in 2016-'17 before joining the Blues' staff as an assistant coach in the summer of 2017.
The Blues are expected to hold a press conference with Berube and President of Hockey Operations and General Manager Doug Armstrong on Tuesday morning in St. Louis. It will be a quick turnaround for the club, which is set to head to Nashville for a game against the Predators on Wednesday night.
