Packers running back AJ Dillon was placed on injured reserve with no designation to return, ending his 2024 season before it begins.Dillon, 26, finished last season on IR with a neck stinger, the same injury that will prevent him from suiting up as the primary backup to new starting running back Josh Jacobs this season.Rookie third-rounder MarShawn Lloyd and Emanuel Wilson are listed as the primary backups for the Packers, who parted with longtime starter Aaron Jones.Lloyd’s availability for Week 1 has been questioned because of a hamstring injury, but he avoided starting the season on the physically unable to perform list.Dillon had 613 rushing yards last season and was lauded for his success in short-yardage since joining the Packers as a second-round pick in 2020.He has 2,428 yards and 16 touchdowns with the Packers.
