The Green Bay Packers believe running back Aaron Jones suffered a sprained MCL during Sunday's game against the Seattle Seahawks, per ESPN's Adam Schefter.
Jones will undergo further testing to confirm the injury, although the Packers ruled him out for the remainder of the contest.
The 26-year-old entered play with 516 rushing yards, 237 receiving yards and seven total touchdowns.
The former UTEP star broke out after getting a chance as the Packers' unquestioned No. 1 back in 2019, gaining 1,558 yards from scrimmage and scoring an NFL-high 19 touchdowns to help the Packers go 13-3, win the NFC South and reach the NFC Championship Game.
