"Elvis Dumervil has been a leader for us on and off the field. He has made a positive impression on our franchise, and we have been fortunate to have him as a Raven," general manager Ozzie Newsome said.
"We respect his professionalism and the way he plays the game, in addition to his extensive charitable efforts that have greatly impacted our Baltimore community and his parents' native country of Haiti. We have not closed the door on the possibility of him returning in the future."
Dumervil thanked the Ravens and their fans in a tweet Wednesday:
Dumervil became a prime salary-cap cut because of his age (33), declining sack numbers (a career-low three last season) and high cap figure ($8.375 million).
By parting ways with Dumervil, the Ravens will create $6 million in cap room. Dumervil represented the biggest cap savings on the Ravens' roster this offseason.
The Ravens signed Dumervil in 2013 after his fax fiasco with Denver made him a free agent. He went to the Pro Bowl in two of his four seasons in Baltimore and set the Ravens' franchise record with 17 sacks in 2014.
But Dumervil had only nine sacks in the past two seasons. He was limited to eight games last season after undergoing offseason surgery on his Achilles and estimated that he was 85 percent healthy.
Dumervil's 99 sacks rank as the third most among active players since the start of 2006 (his first season in the league), and his 31 multiple-sack games are tied with DeMarcus Ware for the most over that same span.
