Veteran pass rusher Antwan Barnes is drawing interest from NFL teams with several teams dealing with injuries to their front seven, according to sources. The former Ravens, Chargers and Jets pass rusher is on NFL teams' radar as they look for pass rushers. Two years ago, Barnes has suffered a season-ending knee injury and was placed on injured reserve. Barnes was primarily a backup that came in during pass rushing situations. He had two sacks for the 2013 season. Barnes, 30, has 25 1/2 career sacks, five forced fumbles and one interception in eight NFL seasons.
