Davis, 27, entered the NFL in the second round of the 2016 draft with the Pittsburgh Steelers at No. 58 overall. The 6-foot-1, 202-pound Maryland product has also been a member of the Washington Football Team, Indianapolis Colts and Cincinnati Bengals.
Through 73 games and 47 starts, including postseason, Davis stands with 287 tackles, 3.5 sacks, one forced fumble, two fumble recoveries and five interceptions in his career.
Davis returned for a second stint with Pittsburgh last season, playing 47 percent of the snaps on special teams. He’s since spent September and October between the Indianapolis and Cincinnati practice squads, serving as a standard elevation to the gameday roster for both organizations.
New England’s scout team currently stands at 16 following the reversions of defensive back Myles Bryant and interior offensive linemen James Ferentz, Will Sherman and Alex Redmond.
