If there were any worries from Arizona Cardinals fans about David Johnson’s status for 2017 following a season-ending knee injury, the running back just dumped some water on them—literally.

Johnson has been rehabbing from an MCL sprain suffered in Week 17 of the season, which the Cardinals announced wouldn’t require surgery.

When it comes to MCL sprains, it could mean two weeks or over two months of rehab depending on the grade of the injury, according to Michael Conlon, a physical therapist and founder of Finish Line Physical Therapy in New York City, who spoke to Men’s Fitness about Steph Curry's injury in the 2016 NBA playoffs.

Fortunately for the 6'1", 225-lb running back, his strain was not considered a serious one. Head coach Bruce Arians said that Johnson would need around two months of rehab for the injury, but just six weeks later, he looks ready to get back on the field.

The running back posted a video on social media—which he enjoys doing, like the time he crushed 500-lb back squats and 51-inch box jumps—of him jumping out of a rehab pool at the Cardinals training center.

Let’s just say he looked pretty strong:

 

Knee showing great progress!

Johnson had a fantastic offensive season for the Cardinals, gaining 2,118 yards from scrimmage with 20 total touchdowns, earning his first career Pro Bowl and All-Pro selections. He also set an NFL record by gaining at least 100 yards from scrimmage in 15 straight games.

The former Northern Iowa star became the first NFL player to have at least 2,000 total yards and 20 touchdowns since 2006, when recent Pro Football Hall of Fame inductee LaDainian Tomlinson did it with the Chargers.

How did Johnson have so much production in 2016? Never skipping leg day probably helped:

Those big lifts on leg day are probably why Johnson can get vertical and make amazing plays like this one, where he leapt over a Carolina Panthers defender in Week 8 of the season:
