The Devils fired coach John Hynes on Tuesday, after a awful start to a season that began with higher expectations has left the club near the bottom of the National Hockey League standings and searching for answers.
Assistant Alain Nasreddine was named as his replacement; Peter Horachek, who had been a pro scout for New Jersey, will be an assistant under Nasreddine.
The Devils (9-13-4) are last in the Metropolitan Division and 30th in the league, their season hanging by a thread after a busy offseason.
Hynes, 44, finishes with a 150-159-18 record during his time with the Devils.
The Devils qualified for the Stanley Cup Playoffs once under Hynes, losing to the Tampa Bay Lightning in five games in the Eastern Conference First Round in 2017. Shero hired Hynes to be the head coach less than a month later, on June 2.
