ALAMEDA — The Raiders know the day they are playing the San Diego Chargers this week. Now it's a matter of finding out the starting time.

The holdup is over what time the A's play their second playoff game at the Coliseum, on Saturday.

If the start time is in the late afternoon or evening, converting the Coliseum from a baseball configuration to a baseball one by Sunday at 1 p.m. poses logistical problems.

Raiders coach Dennis Allen said he was told that the Raiders will know the starting time for their game as soon as today and as late as Wednesday.

The field conversion time takes as long as 18 hours. If there isn't enough time, the NFL intends to move the Raiders-Chargers game to Sunday night.
