The Redskins were reportedly trying to trade Brown in recent days, but it looks like there was no deal to be made before the start of free agency.
Brown, 29, is a former second-round pick of the Titans back in 2012. He finished his four-year rookie contract with Tennessee before signing a one-year, $1,250,000 contract with the Bills as an unrestricted free agent in 2016.
After finding less interest than anticipated, Brown agreed to a one-year, $2.3 million contract with the Redskins in 2017 and returned to Washington this last year on a three-year contract worth up to $24 million.
According to OverTheCap.com, releasing Brown will free up $5.75 million of available cap space while creating $3 million in dead money.
In 2018, Brown appeared in all 16 games for the Redskins and recorded 96 tackles, one sack, two forced fumbles, and a pass defense. Pro Football Focus has him rated as the No. 3 linebacker out of 92 qualifying players.
