Sharks fire head coach Boughner
Assistant coaches John Madden, John MacLean, and Dan Darrow were also let go.
Boughner took over behind San Jose's bench during the 2019-20 campaign and had one year left on his contract. He posted a 67-85-23 record through 175 games with the club and never qualified for the playoffs.
San Jose is also seeking a new general manager. Joe Will held the position on an interim basis this past season after 19-year veteran Doug Wilson stepped down.
"As we progress through our search for the next general manager of the Sharks following 19 seasons under Doug Wilson's leadership, it has become apparent that the organization is in the process of an evolution," Will said.
"The bottom line is we have missed the playoffs for the past three seasons, which isn't acceptable to our owner, our organization, or to our fans. As part of this evolution and evaluation, we felt it was in the best interest of the club to allow the next Sharks general manager to have full autonomy related to the makeup of the on-ice coaching staff moving ahead."
The NHL's coaching carousel has been in full swing since the regular season ended, with nine clubs making changes behind the bench.
