The Pittsburgh Penguins fired coach Mike Sullivan, who won back-to-back Stanley Cup titles in his first two seasons, the team announced Monday.

In a move that signals the end of a storied chapter, the Pittsburgh Penguins have officially split with head coach Mike Sullivan, a two-time Stanley Cup champion. The decision, reported by AP News, marks a dramatic shift for a franchise looking to reclaim its former dominance.

The decision ends a fantastic run by Sullivan, who was hired by the franchise during the 2015-16 season after it fired Mike Johnston. In Sullivan's first year with the team, the Penguins won the Stanley Cup. They did it again the following year, giving Sullivan two championships in his first two seasons with the franchise.
