ALLEN PARK, Mich. (AP) - The Detroit Lions put rookie running back Kerryon Johnson on injured reserve with a knee injury.
Detroit also activated returner Jamal Agnew from IR on Wednesday. Agnew has been out since Week 5 because of a knee injury. He was an All-Pro last season as a rookie after returning two punts for touchdowns.
Johnson ran for 641 yards and three scores before his injury last month. He also had 32 receptions for 213 yards and a score. Johnson ran for a season-high 158 yards in a win at Miami and had 101 yards rushing in a victory over New England.
Detroit added depth at running back by signing running back Justin Stockton to the practice squad and cutting guard Salesi Uhatafe from it.
