ASHBURN, Va. (AP) - A swollen knee has kept Albert Haynesworth from taking his conditioning test, sidelining him from Washington Redskins training camp practice for the third straight day.

Coach Mike Shanahan says Haynesworth showed up Saturday morning with some irritation in his knee and that doctors recommended he not take the test.

Shanahan is requiring that Haynesworth pass the test before taking part in practice. The coach is requiring him to do so because the defensive lineman did not take part in the team's offseason conditioning program.

Haynesworth failed the test Thursday and Friday.

Haynesworth did make his first appearance on the field during a practice Saturday morning, standing to the side and watching drills for about 10 minutes.
