The Lions and executive Brian Xanders have parted ways, as Neil Stratton of Inside The League tweets. Xanders’ departure has been confirmed by Justin Rogers of The Detroit News (Twitter link). 
Xanders was hired by the previous regime in Detroit to serve as the club’s senior personnel executive. With no connections to current GM Bob Quinn, he lost some of his power in the last year and he’ll look for a better opportunity.
From 2009 through 2012, Xanders served as the Broncos’ GM. In recent years, he has been in the mix for multiple top jobs, including the Dolphins’ GM job in 2014 and the Browns’ search for a lead exec last year.
Former Lions GM Martin Mayhew is now with the 49ers’ Senior Personnel Executive, so that could be one potential fit for Xanders as he looks for his next job.
