The 49ers have signed not one, but two, tight ends to address their recent shortage at the position. The team today inked both Gijon Robinson, who played at Missouri Western, and Joe Sawyer, who played at Southwest Missouri State, to deals. To make room on the roster, they cut guard Garrett Chisolm. Nate Byham, who is coming back from an ACL injury, and Delanie Walker, who suffered a knee injury Sunday, are not practicing today. Because they are recent signees, neither Robinson nor Sawyer can practice in pads initially. Source: Sacramento Blog
