Panthers place Jaycee Horn and Mick Jackson Jr. on IR before Week 4

The Carolina Panthers will be without cornerbacks Jaycee Horn and Mick Jackson Jr. as they head into their Week 4 matchup against the Detroit Lions on Sunday. Both players were placed on injured reserve on Wednesday, meaning they will miss at least four games. Horn is dealing with a significant quad injury sustained during the team’s Week 3 loss to the Cleveland Browns, while Jackson Jr. has a groin injury. This development leaves the Panthers' secondary significantly weakened as they prepare for a tough opponent. The team has signed wide receiver David Moore, running back Anthony Tyus III, and added defensive back Robert Rochell to the practice squad as they look for depth in the secondary ahead of this weekend's game.
