The Washington Post is reporting that Redskins defensive tackle Albert Haynesworth has rhabdomyolysis. The report comes one day after Haynesworth accused coach Mike Shanahan of underplaying his medical condition. The condition, which sidelined Haynesworth in practice last week, causes the rapid breakdown of skeletal muscle due to injury to muscle tissue, according to three sources. A Redskins official told ESPN that the team is unaware that Haynesworth has this condition.
