The Bears made two signings Sunday designed to strengthen their special teams and depth on defense, adding former Chiefs S Jordan Lucas and ex-Texans OLB Barkevious Mingo on one-year deals, per multiple reports.

Lucas, fresh off winning a Super Bowl under Andy Reid's Chiefs, played the majority of his snaps last season on special teams but filled in two years ago on defense with the first four starts of his career. The 6-foot-1, 200-pound Lucas, a sixth-round pick of the Miami Dolphins in 2016, has played in six combined postseason games in his first four seasons — the same number in which the Bears have appeared in the past 14 years.

Mingo, selected out of LSU sixth overall in the 2013 draft by the Cleveland Browns, recorded five sacks as a rookie but no more than two in any of his six seasons, including the past three with the Texans, Seahawks and Colts, respectively. But the 29-year-old edge who measures in at a long and lean 6-foot-5 and 235 pounds, has developed into a solid special teamer, including under the tutelage of Bears special-teams coordinator Chris Tabor when he held the same post in Cleveland, and Chuck Pagano, the Bears defensive coordinator who oversaw Mingo in his final season as Colts coach in 2017.

Mingo was part of the Jadeveon Clowney blockbuster trade last offseason, going from Seattle to Houston, where he topped 300 special teams snaps for the fourth time in his career. He'll add more athleticism in the Bears OLB3 role than Aaron Lynch, in addition to providing a dependable presence on a Bears third phase that was much improved last season.

While Mingo clearly will be a defensive reserve behind star pass rushers Khalil Mack and newcomer Robert Quinn, it's the Bears envision Lucas in a starting role. Since Ha Ha Clinton-Dix's free-agent departure for Dallas after starting all 16 games and logging the second-most snaps on defense last season, the Bears have re-signed key reserve Deon Bush and added Lucas, who have a combined seven starts over the past two seasons but only 13 total in their respective four-year careers.
