The Ravens are always looking for developmental pass rushers and they added another one to their roster Monday, signing undrafted free agent Da'Sean Downey. Downey played at the University of Massachusetts. As a senior last year, he had six sacks, 58 tackles and 20 tackles for loss, the second most by a player in program history. The 6-foot-4, 225-pound defensive end was a first-team Eastern College Athletic Conference selection. A New York native, he started 25 games in college. He finished with 12 sacks, 184 tackles, 34 tackles for loss, six tackles defended and four forced fumbles. Downey will most likely be used as an outside linebacker in the NFL.
