The Miami Dolphins fired offensive line coach Mike Maser after just one season with the team.
The move was first reported by ESPN senior NFL analyst Chris Mortensen.
Maser was the first assistant hired by then-new coach Tony Sparano a year ago. He previously was an offensive line coach for the Carolina Panthers from 2003 to 2006; for the Jacksonville Jaguars from 1995 to 2002; and at Boston College from 1981 through 1993.
The offensive line is considered one of the Dolphins' weakest areas, despite the addition of tackle Jake Long, the first overall pick in the 2007 draft. Miami struggled to run consistently from its base offense last season.
The Dolphins were the NFL's No. 11 rushing offense in 2008, averaging 118.6 rushing yards per game, and the 12th-best offense overall with 345.6 yards per game.
