PHILADELPHIA -- The New England Patriots acquired nose tackle Isaac Sopoaga from the Philadelphia Eagles along with a sixth-round pick in 2014 for a fifth-rounder next year.
Sopoaga, who spent his first nine seasons with San Francisco, had signed an $11 million, three-year deal as a free agent. He played eight games and 18 tackles.
The 32-yar-old Sopoaga helps replace Pro Bowl nose tackle Vince Wilfork, who is out for the season. The Patriots have allowed 157 yards rushing per game since Wilfork was injured.
Rookie third-round pick Bennie Logan, veteran Clifton Geathers and rookie Damion Square will get more playing time with the Eagles now that Sopoaga is gone.
The Patriots have also lost right tackle Sebastian Vollmer for the season with a right leg injury.
Vollmer was placed on injured reserve on Tuesday after being hurt in the second quarter Sunday when Miami defensive tackle Randy Starks fell on the back of his legs. Marcus Cannon replaced Vollmer and the Patriots came back to defeat the Dolphins 27-17.
Vollmer, a second-round draft pick by the Patriots in 2009, has started all eight games this season and 57 of the 64 he's played in the NFL, including the postseason.
