The Bears picked up some defensive line depth Tuesday, signing tackle Andre Fluellen and end Kyle Moore. They also added center Taylor Boggs.

All three players signed one-year contracts.

The 6-foot-6, 263-pound Moore could provide the most help. He has started 14 games in four seasons with Tampa Bay Buccaneers (2009-10) and Buffalo Bills (2011-12). The former fourth-round pick (117th overall) out of USC started seven games last season and had a career-high 24 tackles and 3 sacks in addition to 22 quarterback pressures.

The 6-foot-2, 302-pound Fluellen started six games and has played in 56 with the Detroit Lions (2008-12) and Miami Dolphins (2012). He was the Lions' third-round pick (87th overall) in '08 out of Florida State. He has 52 career tackles and 2½ sacks and played in just five games with one start and 6 tackles last season, splitting time with the Lions and Bucs.

Since last season the Bears have released defensive tackle Matt Toeaina. And tackle Amobi Okoye remains an unrestricted free agent, as does Israel Idonije, who was second on the team with 7 ½ sacks last season. Idonije is primarily an end but has also played tackle in nine seasons with the Bears.
