The Chicago Bears claimed linebacker Mykal Walker off waivers on Monday, the team announced.
Walker, who started 12 games for the Atlanta Falcons last season, was waived by the team on Sunday.
Last season, the 25-year-old Walker posted a career-high 107 tackles with four tackles for loss, his first career sack and two interceptions. It had been Walker's first year as a full-time starter after two seasons as a rotational player who picked up spot starts.
In his Falcons career, Walker played in 49 games for Atlanta with 20 starts, three interceptions and a sack.
