Detroit Lions running back Kerryon Johnson suffered a knee injury in Sunday's game against the Carolina Panthers, and the early prognosis is relatively positive.
According to Ian Rapoport of NFL Network, the team believes the injury is just a sprain and not a torn ACL, although he will have an MRI Monday.
Johnson had 87 rushing yards and a touchdown before coming out in the second half.
The 21-year-old joined the Lions as a second-round pick out of Auburn, and the team's willingness to spend a high selection on him signaled he would be installed as the team's featured rusher.
