ASHBURN, Va. — Washington Redskins defensive tackle Albert Haynesworth has been sent home from practice.

Coach Jim Zorn told reporters Friday he sent home Haynesworth for disciplinary reasons. Zorn says Haynesworth will still play Sunday against the Dallas Cowboys but might not start.

Haynesworth was fined $10,000 by the NFL on Thursday for an altercation with Giants running back Brandon Jacobs late in New York's 45-12 victory at Washington.

Haynesworth signed a seven-year, $100 million contract with Washington, with $41 million in guaranteed money, during the offseason.
