Ravens defensive tackle Casey Walker signed his $510,000 exclusive-rights free agent tender.
Walker is entering his second NFL season. He was signed after a stint with the New England Patriots, and made one tackle for the Ravens in one game.
With the Patriots, Walker had 11 tackles and one sack in five games, including one start. He played collegiately at Oklahoma.
The lone remaining unsigned exclusive-rights free agent is running back Fitz Toussaint, who was assigned a $510,000 tender after playing in four games last season and rushing for 12 yards on six carries and catching three passes for 27 yards.
