The Baltimore Ravens, having already lost several pieces from last season's Super Bowl team (at least they got their franchise quarterback Joe Flacco signed long-term because can you imagine?), are forced into improvised rebuilding mode. Following a three-year deal with defensive lineman Chris Canty and several others earlier this week, the Ravens announced on Friday that they've signed former Cowboys linebacker Marcus Spears.

According to multiple reports the contract is worth $3.55 million over two years. A former first-round selection out of LSU, Spears has generated 225 career tackles and ten quarterback sacks. Writes Aaron Wilson with the Baltimore Sun:

Ravens general manager Ozzie Newsome has made strengthening the defensive line a priority and has already signed former New York Giants defensive tackle Chris Canty to a three-year, $8 million contract since the start of free agency.
