The Ravens have waived defensive tackle 
Walker had just made his training camp debut during Monday’s M&T Bank Stadium practice after coming off the active physically unable to perform list. He missed the first four practices of camp due to a knee injury.
Walker played in one game for the Ravens last year and made one tackle. He played in five games with the Patriots before joining Baltimore and made 11 tackles and one sack.
The Ravens have signed defensive tackle Micajah Reynolds to take Walker’s place on the roster. While Walker was a 6-foot-1, 340-pound tackle, Reynolds steps in at 6-foot-5, 330 pounds.
Reynolds is a Michigan State product who spent some time with the Miami Dolphins in training camp last year. He played in one of their preseason games. Reynolds then joined the Las Vegas Outlaws of the Arena Football League.
Reynolds, who notched 58 career tackles at Michigan State, helped save a teenager’s life during his senior year of college, per USA Today. He pulled over to help a teen who had been shot multiple times on the side of the road.
