Jackson rushed 13 times for 31 yards and a touchdown across nine appearances in 2021.
Jackson established himself as the Colts' No. 3 running back behind Jonathan Taylor and Nyheim Hines during the second half of the 2021 campaign, but he still played primarily on special teams. While the 22-year-old reached the end zone Week 13, Jackson wasn't a reliable fantasy contributor while serving in a depth role.
