Even when entirely healthy Oakland's passing game has struggled. The Raiders are 28th out of 32 teams in throwing the ball, averaging only 167.7 yards a game. They've also struggled to get into the end zone in their last three games.
Coach Lane Kiffin announced a change in quarterbacks in an effort to spark the offense, but Josh McCown might not have a healthy complement of receivers to work with.
Williams was released earlier this week in order to make room for Dwight, who originally interested the Raiders as a kick returner. But Williams dropped several passes over the first seven games and had not made much of a positive impact on the offense.
How much help Dwight will be is debatable. He hasn't played since suffering a season-ending foot injury with the Jets early in 2006 and has only 188 career receptions. He's also trying to learn a new offense, which won't be easy.
Curry has been limited in practice all week but said he expects to play on Sunday.
