The Jacksonville Jaguars have placed cornerback Tyson Campbell on injured reserve due to a hamstring injury sustained in their Week 1 loss to the Miami Dolphins. Campbell will miss at least four games, with a potential return not expected until Week 6, coinciding with the team's trip to London. This marks the second consecutive year Campbell has dealt with a hamstring issue, having missed six games last season. The Jaguars have signed Tre Flowers from the practice squad to fill Campbell's spot and will rely on Ronald Darby and De'Antre Prince as primary cornerbacks during his absence. Campbell, who recently signed a four-year, $76.5 million contract extension, had established himself as a key player on the Jaguars' defense, recording six interceptions and significant tackles over his career. Head coach Doug Pederson has not yet confirmed Campbell's expected return timeline, adding to uncertainty regarding the team's defensive depth.
