The 49’ers made a minor roster today, picking up just released kick returner Allen Rossum, who was let go by the Steelers on Saturday. Rossum was a late training camp addition for the Steelers, and was their primary kick returner last season, taking one back against the 49’ers for a touchdown in their week three contest at Heinz Field. Overall, Rossum took back 38 kicks for 885 yards for a 23.3 average. He also plays conerback, but really plays that role on a limited basis. Last season at corner he made just five tackles for the Steelers.
