Carolina Panthers running back Christian McCaffrey has one of the heaviest workloads in the NFL, so whenever he has any sort of soreness, precaution must be taken.

Take Wednesday, for example, when McCaffrey was limited in practice due to a knee issue, per Josh Alper of Pro Football Talk.

Panthers head coach Ron Rivera did not seem worried about his star rusher, saying that he should be ready to go against the Tennessee Titans on Sunday, but any time McCaffrey is not a full participant in practice is worth noting.

McCaffrey is coming off of a Week 8 performance in which he carried the ball 14 times for 117 yards and a touchdown while logging four catches for 38 yards in a 51-13 loss to the San Francisco 49ers.

On the season overall, McCaffrey has rushed for 735 yards and eight scores while averaging 5.2 yards per carry. In addition, he has caught 39 passes for 343 yards and a couple of touchdowns.

The 23-year-old has reached the end zone in five straight games and is widely considered an MVP candidate thus far.

McCaffrey, who played his collegiate football at Stanford, was originally selected by Carolina with the eighth overall pick of the 2017 NFL Draft.

He played in all 16 games during his rookie campaign but was relatively quiet as a rusher, totaling just 435 yards and two touchdowns while posting 3.7 yards per attempt. He did, however, haul in 80 receptions for 651 yards and five scores.

Then, last year, McCaffrey broke out, racking up 1,098 yards and seven rushing touchdowns while snaring 107 balls for 867 yards and six scores.
