ALLEN PARK -- The Detroit Lions' top brass is safe, including president Tom Lewand and general manager Martin Mayhew. They will spearhead the search for a new coach after the firing of Jim Schwartz.

But at least two others were not spared. Offensive coordinator Scott Linehan and receivers coach Tim Lappano were dismissed Monday in the wake of the Schwartz firing.

Mayhew and Lewand made those moves during meetings at Lions headquarters in Allen Park.

The rest of the staff is safe for now, including defensive coordinator Gunther Cunningham, though their statuses could change depending on who is hired as the next head coach.

"Most of our other assistants are under contract for 2014," Lewand said during a news conference Monday afternoon. "There are a couple of contracts that expire at the end of January, and we've been in touch with each of our coaches. But as of right now, they're all under contract."

Linehan was expected to be out in Detroit due to the continued struggles of Matthew Stafford. The fifth-year quarterback has plateaued since a breakout 2011 season, and was lousy in the second half of this season.

Stafford finished with 19 picks, one short of his career high and sixth most in the league, and completed just 58.5 percent of his passes. That ranked 30th, just behind St. Louis' Kellen Clemens.

Linehan has coordinated offenses for most of the past decade, with stints in Minnesota, Miami and Detroit. He also was St. Louis' head coach from 2006-08.

Lappano also was a member of Schwartz's first staff, though he worked with the tight ends his first four years. He was in his first year with the receivers.

Detroit now is seeking its third receivers coach in as many years.

Cunningham, Kris Kocurek (defensive line), Jeremiah Washburn (offensive line), Bradford Banta (assistant linebackers), Todd Downing (quarterback) and Matt Burke (linebackers) are the remaining members of Schwartz's original 2009 staff.
