Source: Haynesworth failed 3rd sprint

Updated: July 31, 2010, 1:25 AM ET

Albert Haynesworth's inability to run a third 300-yard sprint in a satisfactory time in the eyes of coach Mike Shanahan prevented him from practicing with the Redskins Thursday.

Haynesworth had to pass a conditioning test Thursday and he entered the day planning to do two sprints. According to a source, Shanahan believed Haynesworth had too much rest time between his runs and asked for a third.

Haynesworth failed the third sprint. A source said Haynesworth told Shanahan he never ran three such sprints during his best Pro Bowl seasons. Shanahan then told Haynesworth that he must not have ever been in shape, according to the source.

"The bottom line," Shanahan said, "is we're going to get him in shape."

Shanahan and Haynesworth have been feuding since Shanahan became coach of the Redskins in early January. Haynesworth skipped all offseason work with the team because he didn't want to be in the team's new 3-4 defensive scheme.

Haynesworth reported to the team Wednesday 30 to 40 pounds lighter but was told he would work with the backups when he returned to the field.

Haynesworth's only appearance came after the practice was over, when he spent about 20 minutes walking through some plays with two assistant coaches. Looking perhaps 30 pounds leaner than he did a year ago, Haynesworth hovered around large upside-down trash bins -- representing offensive linemen -- as he learned the defense's terminology. He didn't speak to reporters.

Shanahan said Haynesworth will take the test once a day until he passes. If Haynesworth fails, he'll have to spend extra time on the treadmill -- as he did Thursday -- and will continue to be absent from practice.

Haynesworth boycotted the team's offseason workouts and minicamps because he is unhappy with the Redskins' switch to a 3-4 defense and wanted a trade. When he finally returned to Redskins Park on Wednesday, he was told he would have to pass the conditioning test to take part in training camp and would start off practicing with the reserves.

Haynesworth was the only player required to take the test. Everyone else on the team attended a certain percentage of offseason workouts required by Shanahan.

"The conditioning test, I don't even think a lot of us guys that were even here 100 percent could have passed that thing," cornerback DeAngelo Hall. "But that's what conditioning tests are, that's what they're supposed to be, they're supposed to be some of them unattainable. Some we've had in the past were definitely unattainable."

But Shanahan maintained that Haynesworth was not set up to fail. He said all the other linemen essentially passed the test by taking part in the offseason workouts.

"It's a very fair test," Shanahan said. "But more importantly, it keeps a guy from getting hurt. I don't want to put a guy out there that's not ready to go, and all of a sudden there's a setback for two weeks."

Shanahan's reasoning carried less weight on a day when practice was not particularly demanding, and on a day when receiver Malcolm Kelly was allowed to practice on a wet field despite nursing a sore hamstring. Also, while conditioning tests are routine among NFL teams, failure to pass hasn't necessarily excluded a player from participation. The Redskins had three players fail the test in 2008, but all three took part as usual in training camp practices.

When told he had failed the test, Haynesworth was "first-class all the way" in accepting the news, according to Shanahan. The coach indicated there were no harsh words exchanged.

FoxSports.com first reported that Haynesworth had failed his conditioning test.

Haynesworth doesn't want to play nose tackle in a 3-4 defense and would rather be in a scheme that gives him the freedom that helped make him a dominant player for many years with the Tennessee Titans. But he also declined Shanahan's offer to find another team and accepted a $21 million bonus on April 1, part of the seven-year, $100 million deal signed as a free agent a year ago.

The saga overshadowed the team's start of a new chapter with new coach Shanahan and new quarterback Donovan McNabb. Players have tried to ignore the distraction, but several called Haynesworth "selfish" when he skipped the mandatory minicamp last month.

"The sooner all this gets behind us," center Casey Rabach said, "it'll be better for this team."

Notes

CB Carlos Rogers signed his $1.54 million restricted free agent tender and took part in practice. He waited until the last possible moment because he was unhappy not to get a long-term contract. ... OL Mike Williams, who is being treated for blood clots, was placed on the reserved non-football illness list. ... No. 4 overall draft pick Trent Williams is officially a holdout, missing the first day of camp while contract negotiations continue. "I'd be surprised if he's not in here quickly," Shanahan said.
