McCaffrey was unable to practice Wednesday due to a shoulder injury, Max Henson of the Panthers' official site reports.
The release of the Panthers' first Week 13 injury report revealed McCaffrey's injury, which stems from Sunday's win over the Jets. According to Joe Person of The Charlotte Observer, head coach Ron Rivera said that McCaffrey was on the receiving end of "a hit" in the contest. While McCaffrey doesn't necessarily need to make an appearance at practice Thursday, he may need to show a degree of progress with the training staff.
