The Redskins solved their second major locker room conundrum in two days by dealing Haynesworth to the Patriots for a 2013 fifth-round pick Thursday.
ESPN's Adam Schefter first reported the development.
Haynesworth set a then-record in 2009 by getting $41 million guaranteed from the Redskins while signing a seven-year, $100 million pact.
But the former all-pro never produced in Washington and repeatedly clashed with coach Mike Shanahan in 2010 over conditioning and his unhappiness with Washington's newly installed 3-4 defense, which Haynesworth felt minimized his talents. He was ultimately suspended for the final four games.
