The Detroit Lions announced on Saturday that they have elevated running back Justin Jackson and linebacker Anthony Pittman to the Week 1 game day, making them eligible to play against the Philadelphia Eagles.
Each week, teams are eligible to elevate up to two practice squad members up to the active roster on game days. In previous seasons, players were allowed two roster elevations during the season before needing to be signed to the active roster, but this offseason, the NFL expanded that number to three total elevations per year.
As the fourth running back on the roster—barring one of the top three being inactive—Jackson is likely being elevated for special teams purposes.
