The Detroit Lions have made another high-level change to their front office, letting go of director of pro scouting Brendan Prophett after three years with the team, a source informed of the decision told the Free Press.

Prophett, who previously worked for the New Orleans Saints and New York Jets, was one of Bob Quinn's first hires as general manager in 2016 and is the second such person to be let go this year.

The Lions also fired lead contract negotiator Matt Harriss in January and named Mike Disner their new vice president of football administration days later.

Prophett, whose firing was first reported by football industry website Inside the League, was one of the highest-ranking members of the Lions' personnel department, behind only Quinn, vice president of player personnel Kyle O'Brien and director of player personnel Lance Newmark.

He did not return a phone call seeking comment Tuesday, but had a strong reputation across the league as being a good communicator and someone who was honest with his player evaluations.

The Lions had three relatively uninspiring free-agent periods with Prophett in charge of pro personnel before spending big to land defensive end Trey Flowers, tight end Jesse James and cornerback Jutin Coleman last month.

They made Flowers the fifth highest paid defensive player in the NFL, gave Coleman the richest contract for a slot cornerback and signed James to a four-year, $28.5 million deal.

Last year, the Lions found sack leader Romeo Okwara on the waiver wire in September and re-signed Zach Zenner, their third leading rusher, as a street free agent in November.
