The deal reportedly features a $7.5 million signing bonus and a $1 million 2013 base salary.
A three-time Pro Bowler, Dumervil recorded 11 sacks in 2012.
Dumervil’s departure from Denver takes place just 10 weeks after Baltimore shocked the Broncos, 38-35 in double-overtime in the second-round of the AFC playoffs.
A botched fax transaction forced the Broncos to terminate Dumervil’s contract if the team was to avoid paying his $12 million salary.
