Cut by the Ravens on Wednesday, free safety Michael Huff and defensive lineman Marcus Spears went unclaimed off waivers.
The veteran defenders are now unrestricted free agents.
Huff was signed to a three-year, $6 million contract, including a $1.5 million signing bonus in March. He was benched after he struggled mightily in the Ravens' season-opening 49-27 loss to the Denver Broncos.
Spears was signed to a two-year, $2.75 million contract in March that included a $600,000 signing bonus.
The Ravens are now $1.797 million under the NFL salary cap limit of $123 million following the roster moves, which included promoting safeties Omar Brown and Brynden Trawick from the practice squad to the active roster.
