Last week, the Raiders released safety Gibril Wilson, wide receiver Ronald Curry and defensive end Kalimba Edwards. The five releases have saved the team $14.6 million in cap room, but it has also put $11.5 million of dead money onto their $123 million cap. If you include the carryover cap losses from DeAngelo Hall, who was cut last year, the Raiders have close to $20 million of dead money on their salary cap.
Harris was signed last year from the San Francisco 49ers. He signed a three-year, $14 million contract and was due a $6 million roster bonus by the end of the week.
Harris struggled late in the season with his blocking and with penalties.
Griffith tore up his knee against Baltimore on Oct. 26, would have counted just over $1 million against the cap. The Raiders also have a replacement on hand in Oren O'Neal.
Owner Al Davis has now cut ties with almost all the big-money free agents he brought in last offseason.
The only one remaining is receiver Javon Walker, who could be gone before collecting a $5 million bonus payment on March 3. Walker had just 15 catches for 196 yards last season after signing a $55 million, six-year deal. He missed the final seven games of the season with an ankle injury.
