Assistant director of player personnel Mike Baugh and college scouting coordinator Rick Thompson also departed.

Also at risk of being fired was coach Cam Cameron, who said he would discuss his future with Parcells this week. On Sunday, the Dolphins became only the eighth team to finish 1-15.

Parcells began work Thursday as executive vice president of football operations.

Mueller was the Dolphins' general manager for three seasons but was in charge of personnel decisions only since coach Nick Saban left a year ago.

Mueller received mixed reviews for his moves in 2007, which included the acquisition of free-agent linebacker Joey Porter and the selection of receiver Ted Ginn Jr. and quarterback John Beck in the draft.
