Xenith's decision comes three days after Brown was accused of rape by his former trainer Britney Taylor. Brown allegedly sexually assaulted Taylor on three separate occasions from 2017-18 and culminated in a rape in May 2018.
Brown's attorney Darren Heitner denied the allegations on Tuesday night.
The Central Michigan product chose to wear the Xenith Shadow helmet as a member of the Raiders. But Oakland released Brown on Sept. 7 following a series of incidents with general manager Mike Mayock and head coach Jon Gruden.

New England is 1–0 entering Sunday after a win over the Steelers in Week 1.
