Cardinals running back David Johnson suffered a scaryknee injury in Week 17 of his breakout season. Fortunately for Johnson and the Cardinals, the injury looked way worse than it actually was. It was a sprained MCL that did not require surgery.

Still, Johnson has needed to spend the offseason rehabbing the knee, and he seems to be making incredible progress. He can do this just one month after suffering the injury:

Jumping out of a pool is difficult to do when your knee is at 100 percent, and Johnson can do thatwhile rehabbing an injury.

Cardinals fans have to be pleased with that progress.
