Football: Raiders' Walker perplexed by inactivity

ALAMEDA, Calif. (AP) - Javon Walker's surgically repaired knee is fine. He runs without a hitch and can break in and out of his cuts fluidly.

The Oakland Raiders veteran wide receiver just can't get on the field.

While coach Tom Cable tries to figure out how to inject life into the NFL's 31st-ranked offense, Walker spends his afternoons lining up with the scout team in practice.

Just shy of 31, Walker understands the Raiders' decision to start younger receivers but believes he can contribute more by playing than watching from the sidelines.
