With the Raiders' return game hurting almost as much as Jacoby Ford's left foot, Oakland has reportedly signed a new return man in Ford's absence.Pro Football Talk reported Monday evening the Raiders had signed former Buffalo return specialist Roscoe Parrish, who was cut by San Diego earlier in the day. The Raiders have not announced any signing but if true, the team would have to make a corresponding roster move since its roster was at the NFL-mandated maximum 75 players.Parrish, 30, has averaged 12.0 yards on 135 punt returns in his seven-year career, leading the league with averages of 16.3 yards in 2007 and 15.3 yards in 2008, with three touchdowns.In three preseason games, the Raiders have averaged 4.4 yards per punt return.Parish, a second-round draft pick by Buffalo out of Miami in 2005, has also averaged 23.6 yards on 29 career kickoff returns, though none since 2009.Earlier in the day, Raiders coach Dennis Allen was asked if his opening night returner might not even be on the team's roster at that point."That's a possibility, yeah," Allen said. "That's a possibility. Again, we're going to go through everybody's cuts from today (and) we'll go through when everybody makes their 53-man cuts, and we're going to see who's out there and if there's somebody that we feel like gives us a chance to win, we're going to go try to get him."
