Several key players from top NFL teams are holding out in contract disputes, which could impact their teams' seasons. The New York Jets' top cornerback Darrelle Revis is holding out and refusing to report to training camp until he gets a new contract. For the San Diego Chargers, linebacker Shawne Merriman has agreed to a new contract but wide receiver Vincent Jackson and offensive tackle Marcus McNeill are still holding out. Offensive guard Logan Mankins is also holding out from the New England Patriots. Defensive tackle Aubrayo Franklin of the 49ers rejected an offer but may sign a new contract soon.
