The Washington Redskins' defensive lineman hurt his ankle during Wednesday's practice and didn't take part in team drills Thursday. Coach Mike Shanahan said he hopes the injury isn't too serious and that Haynesworth might be able to return Friday. Washington hosts Houston on Sunday.
Haynesworth played as a backup in the season opener after months of disagreements with Shanahan over offseason workouts, practices and preseason playing time.
Shanahan said backup linebacker Perry Riley is "ready to go" after recovering from a sprained right foot.
Kareem Moore, a safety who has a sprained right knee, appears unlikely to play against Houston.
