Indianapolis Colts cornerback JuJu Brents has been placed on injured reserve due to a knee injury sustained in the season opener against the Houston Texans. Initially considered minor, an MRI revealed more severe damage, potentially sidelining him for the entire season, although there's a chance he could return by mid-December. To fill the void, the Colts signed strong safety Ronnie Harrison Jr. and cornerback Kelvin Joseph to the practice squad. Additionally, backup cornerbacks Chris Lammons, Samuel Womack, and Dallis Flowers may see increased roles. The injury is a significant setback for a young and thin Colts secondary, already lacking depth and experience. The team is considering various adjustments, including moving veteran Kenny Moore II to an outside cornerback position.
