The move had been speculated for some time, and Jones said in early December he was open to a position switch if it meant more playing time. Jones is fourth on the Raiders' depth chart at running back and has just 22 carries over two seasons.
Jones has experience at cornerback. He played the position in high school and early in his college career at Eastern Washington.
This probably is the right move for Jones, who was unable to move up the depth chart during a season in which the Raiders were hit by injuries in the backfield and finished 28th in the NFL in rushing. He's actually quite fortunate he has another position to fall back on.
