The show's day-to-day boss, show-runner and creator, Remi Aubuchon, has been demoted to writer by producers Brad Grey Television and 20th Century Fox - a radical move to save a show so early in the season.
In Aubuchon's place, writers Kevin Falls and Dan Sackeim have been promoted to co-show-runners, according to Variety.
NBC has been dismayed by "The Lyon's Den's" declining ratings and the fact that it's been regularly beaten on Sunday by "The Practice." (search)
Although NBC yanked its critically acclaimed drama "Boomtown" (search) last week from its Friday-night lineup, it is widely believed that it's keeping "Boomtown" in reserve just in case it eventually decides to pull "Lyon's Den" for low ratings.
"Lyon's Den" was designed as a slick legal series brimming with conspiracy, and as star vehicle to showcase Lowe - who plays an idealistic lawyer pulled into a web of intrigue at a high profile D.C. law firm.
Lowe got the job after leaving "West Wing" (search) -a move many considered to be career suicide.
Show sources said it amounted to sour grapes.
They say Lowe considered himself and Martin Sheen the stars of the show, and that he expected to be paid as much as Sheen.
But by last season, Sheen's role on the show was eventually expanded and he was given a significant raise.
Soon after the rest of the ensemble cast received salary bumps that paid them as much as Lowe - who complained about the situation to producers and eventually quit.
