The team is released the nine-year veteran with a failed physical designation after Burnett failed to receive medical clearance for training camp. Burnett sustained an ankle injury during offseason team activities.
Cutting the veteran will save the Raiders $3.375 million in cash and cap space, according to Brian McIntyre.
Burnett has started 75 games over his NFL career and figures to get another look when healthy again. One potential fit: the Cowboys, who drafted Burnett in the second round back in 2005 and remain desperate for linebacker help.
