The Edmonton Oilers fired general manager Steve Tambellini and replaced him with Craig MacTavish, the team announced Monday.
MacTavish's former role as the Oilers' vice president of hockey operations will be filled by former Columbus Blue Jackets general manager Scott Howson.
The Oilers have had the No. 1 pick in the NHL draft three straight years and continue to struggle. The Oilers failed to reach the playoffs in any season under Tambellini's guidance since 2008-09.
They currently are 12th in the Western Conference standings with 39 points.
MacTavish had previously spent eight seasons (2000-01 to 2008-09) as the head coach of the Oilers and was named the club's senior vice president of hockey operations last summer.
