Source: Redskins plan test for Saturday

ASHBURN, Va. -- The Redskins plan to have defensive tackle Albert Haynesworth take the team conditioning test again Saturday, a source told ESPN NFL Insider Adam Schefter on Friday.

Haynesworth skipped the test, and practice, on Friday, a day after a precautionary MRI exam showed no structural damage on his sore left knee.

Skipping the test for the fourth straight day, Haynesworth's role at practice was limited, to say the least. Other than recovering a few fumbles as part of a turnover drill, he remained a spectator without shoulder pads.

"There's no difference from yesterday," coach Mike Shanahan said. "He's getting treatment and hopefully he keeps on improving."

Haynesworth will not be allowed to practice until he passes the test, which consists of two timed 300-yard back-and-forth shuttle runs.

Haynesworth failed the test each of the first two days of training camp, but his knee has hampered his efforts to try again. He started the test Monday but stopped when the knee acted up.

The persistent soreness prompted the Redskins to order an MRI on Thursday, a test Shanahan called a "preventative measure."

The knee has been bothering Haynesworth for several years, and last year he missed two days of training camp to have fluid injected into the knee.
