The Colts released Harrison on Sunday, Tom Pelissero of NFL Network reports.
After appearing in seven regular-season games for the Colts in 2023, Harrison re-signed with Indianapolis in March on a one-year deal. He was competing for a spot in the Colts' secondary, and across three preseason contests he registered eight tackles (five solo). The 2018 third-round pick will now look to join a team in need of secondary depth should he clear waivers.
