In return for Johnson, the Bucs sent safety Kelcie McCray to Kansas City. The move comes as the Bucs continue to search for depth in the middle of their offensive line.
Since Carl Nicks left the team at the start of training camp due to a toe injury, the Bucs have been experimenting with a variety of players at guard. Oniel Cousins and Patrick Omameh currently are at the top of the depth chart. But Johnson, who also can play center, adds some depth.
Also on Thursday, the Bucs signed guard R.J. Mattes.
