Johnson was promoted from the Seahawks' practice squad Monday, John Boyle of the Seahawks' official site reports.

EDGE Analysis

Johnson's promotion comes with Travis Homer (calf) and Rashaad Penny (hamstring) already being ruled out for the Seahawks' game Monday against Washington. Johnson, who went undrafted out of Louisiana Monroe, has yet to appear in an NFL game. He'll likely be third on the depth chart behind Alex Collins and DeeJay Dallas.
