We've just received the email from New England making the trade with the Raiders for Derrick Burgess official. At the moment, however, we have no further details on what the Patriots have Oakland for the disgruntled eight-year veteran -- the press release simply says "undisclosed draft considerations" were exchanged.

Soon-to-be-ESPN reporter Adam Schefter tweeted that New England and Philadelphia were the two teams trying to acquire Burgess, and that the Eagles had offered a third-round pick and a player, but the Pats' offer must have been better.

Update: Former Raiders exec (and friend of Bill Belichick) Michael Lombardi has Tweeted that New England gave up third- and fifth-round picks in 2011.

Burgess is listed at 6-foot-2, 260 pounds. He first entered the NFL as a third-round pick of the Eagles out of Mississippi in 2001, and signed a free-agent deal with Oakland in 2005; he went to the Pro Bowl in both 2005 and '06, recording a team-record 16 sacks in 2005.

This was to be the final year of the five-year, $17.5 million deal Burgess signed with Oakland, and he had not reported to Oakland's training camp because he wanted a new deal.
