With the team's injury concerns at the moment, they are suddenly in a bit of desperation at the receiver position. Denarius Moore and Jacoby Ford are still not practicing full and Juron Criner now has an ankle injury he's nursing. That leaves the Raiders with just two healthy receivers in Darrius Heyward-Bey and rookie Rod Streater.
If the team signs another receiver before the season opener, it means his salary will be guaranteed the rest of the season. But desperate times call for desperate measures.
This team cannot go into the opener with just two healthy receivers. There is a chance they could get either or both Criner and Moore back by then but neither return is for certain. Ford's prognosis is less positive. He removed the boot from his sprained foot and has been jogging but that is far from a full return.
If the team signs either Underwood or Gaffney, they would have to get up to speed quickly. They will have three days of practice before the game and in a West Coast Offense that requires a lot of timing routes, that prospect is a difficult one.
Gaffney has spent ten seasons in the NFL with four different teams-Houston, Denver, New England, and Washington. He is coming off his best season in which he started all 16 games for the Redskins and totaled 947 yards receiving. He was in Patriots' camp and was released in the final cuts.
Underwood has been in the NFL for three seasons playing for the Jaguars and Patriots. He is more of a return man than he is a receiver. In 2010, he had 24 kick returns for 561 yards (23.4 yards per return). He has caught just 11 passes for 141 yards in his career.
