Jones, 22, left the Packers game against the Chicago Bears Sunday in the first quarter with a knee injury. He was carted off of the field and ruled out for the remainder of the contest before halftime. The Packers also lost running back Ty Montgomery to a rib injury in the first half.
Jones had three carries for 12 yards and one catch for zero yards in the Packers' 23-16 victory at Solider Field in Chicago.
He appeared to suffer the injury while being tackled, when his right foot got stuck in the turft and bent awkwardly underneath his body.
Rookie Jamaal Williams took over running back duties for the Packers Sunday, in the absence of Jones and Montgomery. He ran for 67 yards on 20 carries and pulled in one catch for seven yards in the win.
You should definitely add Williams to your roster in fantasy football. He appears to be in line as the next man up in the Packers' backfield and should see a feature-back-like workload with Brett Hundley at quarterback instead of Aaron Rodgers.
"Jamaal ran hard, ran physical," Packers coach Mike McCarthy told reporters Sunday, according to Packers.com. "Had some overloaded box runs. He had to make hard yards today, and he did a heck of a job with it to keep the sticks moving. I really like the way he played."
Williams could find himself in RB2 territory in good matchups down the stretch. The Packers host the Baltimore Ravens at 1 p.m. Sunday at Lambeau Field. Baltimore has allowed the fourth-most rushing yards to opposing running backs this season.
