The Patriots just announced via their Twitter feed that they have traded for Oakland defensive end Derrick Burgess and released veteran offensive lineman Al Johnson.
The team said the deal was made for "undisclosed draft considerations."
The 6-2, 260-pound Burgess will likely be an outside linebacker and situational pass rusher in the Patriots' 3-4 defense.
A veteran of eight NFL seasons, Burgess has 47 career sacks. He led the NFL in sacks in 2005 during his first season in Oakland (16) to make his first Pro Bowl. He made it back-to-back appearances in 2006, when had he 11 sacks.
Burgess started his career with the Philadelphia Eagles (2001-2004) before going to Oakland as a free agent in 2005.
The 30-year-old Burgess, who is in the final year of a five-year deal, carries a $2 million base salary for 2009.
He had been boycotting Raiders training camp to try to force the Raiders to give him a new deal, release him or trade him.
