Bush and Kansas City agreed to terms on a one-year contract Wednesday, Adam Schefter of ESPN reports.
Bush is coming off a productive 2021 campaign, having notched a career-high 40 tackles (31 solo) to go with nine pass breakups and two interceptions across 14 appearances with Chicago. The 28-year-old, who also boasts plenty of special-teams experience, now looks in line to fill a depth role in Kansas City.
