Hours after agreeing to a two-year deal to bring back veteran Chris Canty, the Ravens added further depth to their defensive line by re-signing defensive end Lawrence Guy to a two-year contract. The 25-year-old was acquired off waivers from the San Diego Chargers early last season and appeared in 11 games, collecting 16 tackles, a pass breakup, and a fumble recovery. Guy surpassed DeAngelo Tyson on the depth chart to emerge as the primary reserve behind Canty at the 5-technique spot in the second half of last season. With young defensive ends Brent Urban and Kapron Lewis-Moore both coming back from serious injuries, the Ravens now have plenty of veteran depth to act as insurance as they revamp a defensive line that no longer includes five-time Pro Bowl selection Haloti Ngata. In his NFL career, the 6-foot-4, 318-pound Guy has totaled 54 tackles, one sack, five pass breakups, and one fumble recovery in 35 games split among Baltimore, San Diego, and Indianapolis.
