The 49-year-old Martindale has coached for seven years in the NFL. He last served as Denver's defensive coordinator in 2010 after spending a year as the team's linebackers coach. He also worked with Oakland's linebackers from 2004-2008.
Martindale also worked as defensive coordinator at Western Kentucky and Western Illinois.
He inherits a linebacking crew that includes two of the best in the game, Ray Lewis and Terrell Suggs. Martindale says signing up with Baltimore was "a no-brainer," adding, "I am thrilled to be a part of a proven system."
