According to Yahoo Sports, the NFL has begun an investigation on if the Washington Redskins tampered with defensive tackle Albert Haynesworth prior to the start of the free agent signing period.
The Tennessee Titans filed charges with the league in late March stating they were interfered with their efforts in re-signing Haynesworth after the 2008 season.
The Washington Post reported:

Haynesworth is among the people expected to be interviewed by NFL officials possibly as early as this week regarding allegations that the Washington Redskins violated league tampering rules, according to league sources.
NFL investigators have been reviewing information relating to the Redskins’ pursuit of Haynesworth, who formerly played for the Tennessee Titans, and whether his representative was improperly contacted before free agency officially began at midnight Feb. 27. The Redskins and Haynesworth agreed to terms of a deal by 5:30 a.m. Feb. 27.
League investigators are interested in obtaining all communications between Haynesworth’s agent, Chad Speck, and Redskins officials in the weeks before free agency opened. Part of the difficulty, though, in determining the subject matter of the contact is that Speck also represents Redskins wide receiver Malcolm Kelly.

If convicted, the Redskins could lose a pick in the 2010 NFL Draft. Last year, the NFL stripped the San Francisco 49ers of a fifth-round draft pick after they ruled the team violated the league’s tampering rules by having an improper conversation with Drew Rosenhaus, agent for Chicago Bears linebacker Lance Briggs, about the player’s upcoming free agent status.

Neither the NFL nor Speck commented on the report or the current investigation.
