PITTSBURGH — The Pittsburgh Steelers (4-0) will be without two starters, receiver Diontae Johnson (back) and veteran right guard David DeCastro for Sunday’s AFC North game against the Cleveland Browns (4-1).

With Johnson out, rookie Chase Claypool, who scored four touchdowns against the Eagles, is slotted for an increased role — as has been the case after Johnson’s back injury and earlier concussion. In Johnson’s absence a week ago, Claypool caught three touchdown passes and rushed for another score, becoming the first rookie in NFL history to do so.
